Read the documentation. Aggressively pursue opportunities to learn new skills.

Get a better paying job once you've got some experience. Raises won't keep up with your value.

Don't work yourself to the bone. There really are plenty of jobs that only require 40hrs/wk and pay the same or better.

Work somewhere with a good culture.

Don't burn out! Ask for help and guidance when needed, and take care of your mental and physical health (get a hobby, go out with friends, go to the gym, etc.)

I've seen brilliant people burn out and end up leaving/missing out growth opportunities because of it. Now that I manage people, it is my biggest area of focus because many times the best employees are the most at risk. They keep getting praise and asked to be involved in more and more and it becomes hard to say 'no' to new projects, responsibilities, etc... Until it is to much.

When it happens everyone looses, your boss, your team, the company, and especially you.

You're not responsible for the bad decisions made by the people who have positional authority over you. Do your best. Warn them about the risks. Let yourself feel disappointed by their decisions, but don't ever accept responsibility for them. If you did your best to warn them, then you took your responsibility seriously. That's enough.

Exercise regularly. Maintain good posture. Stretch. It kills your body, working at a computer all day.

If you're a developer, read the source code. People will tell you how they remember things working, or how they think they should work. The code is what it is.

:wq

Understand that technology cannot fix people problems. Always remember that. If you're asked to solve a people problem and you don't understand it, you will suffer. Only management can fix people problems.

Everyone else here who said, "Keep learning" is right on, but don't forget to work on your soft people skills along with your tech skills. Whether your long term goal is to stay in development or some other aspect of the industry, you should be comfortable talking to all sorts of people (management, sales, customers, etc...), making presentations, being social at conferences and so on. We (techies like me) tend to forget this, but it's really important.

Imagine yourself starting your own company in five years or being the senior manager of a large group. How are you going to like meeting new people every day, selling or at least explaining your product or service to them? If the answer is "not very", then start working on that now.

Ask questions, don't assume. Keep notes of meetings, and notes of your work, little bits. Always have a good rollback plan.

Ask the experts from help, and learn from them. Don't ask things you can legitimately learn really easily on your own by just doing a quick read of the code, but the bar for questions to not be stupid is pretty low. In most projects with any complexity, it's probably overall saving the company money if you ask someone who knows and can save you time, instead of wasting a ton of your time reaching the same conclusion. But next time that problem comes up, you should know how to solve it, so it saves everyone time.

If you have an opportunity to learn a new platform or technology, take it. Every environment has a different way of organizing, implementing, troubleshooting, etc. Each one you learn gives you a new way to look at a project, and teaches you something about how other people may think about projects, problems, and solutions.

People who stick with the same tech for decades are also stuck with the same approach to new projects. When the only tool you have is a hammer, every problem looks like a nail, and all that. Get more tools in your tool belt.

If you're offered a job with more money/benefits or whatever, take it. Don't give your employer the option to counter. And if you ever do let them counter out of curiosity, don't take it... Leave.

There's too many horror stories of people basically staying on after a counter-offer, only to train their replacement and end up tossed out anyways.

Loyalty doesn't mean shit in tech; any promotion you get internally at a job will be pennies compared to what you're able to get by shopping around; so do yourself a favor and run whenever the opportunity arises.

Ultimately tech is a tool to help automate and solve people’s problems. You want to get close to the people your solving problems for so you can get feedback and figure out how to do your job. Your organization may not do this for you. I spend a lot of time on forums listening to my users, and do a lot of extra testing to make sure I’m solving there problems and not making new ones.

I can think of three big pieces of advice:

1. Are you sure? I think the golden age of the magic tech jobs is nearing its end. If you want to join the tech industry because it's an easy ticket for a successful life then you might wanna rethink that. If you want to join the tech industry because engineering is pure magic and you want to be a part of that, then by all means, you do you. Just be ready for it to be a bumpy road if you aren't able to adapt to whatever AI does to the industry over the lifetime of your career.

2. Find companies who will treat you right, and where people are real and do real shit. When I was first starting out, a project I was working on was behind. I stayed over the weekend, even though people told me not to. I finished, I was proud of myself. Then I came in on Monday and everyone else's stuff was behind anyway, so we missed our deadline regardless, and in the end it didn't matter. Right around that time was when I decided, more or less, to hell with this. At the company I eventually jumped ship to, my boss would regularly push back on clients who wanted us to work weekends, come by and encourage people to live a normal life instead of just a working-to-death life. Basically, he looked out for people. So I stayed there for quite a while. Basically, after that experience, if the boss wasn't looking out for me or the tech was shoddy, I bailed instantly. You gotta have a good human life and take pride in what you do.

3. Own up to your fuck-ups. You'll make some. I've destroyed important hardware, made massive architecture mistakes on client work which the clients then identified and talked to us about, deleted the partition table on an important public-facing server, you name it. When I did something like this, I would be 100% upfront about what happened. In good working environments, people would recognize and give respect for that, because nobody's perfect. In bad working environments, being upfront about mistakes would somehow be a bad thing (see point #2). The answer is not to become sneaky. The answer is to leave and go somewhere where people respect honesty. Those places do exist.

Remember tech-companies exist to make money, not to "do good." Whatever problem they are supposedly working on, they are only doing it because someone thinks they can eventually turn it into a revenue stream. Don't drink the kool-aid, be a mercenary and get as much out of it that you can until you can leave for good. Dont' be the like the smuck's that are still working at twitter.

Don't be evil

Don't burn yourself out, document everything.

Set boundaries.

At my first professional job, there was one guy who always came in at exactly on time and never stayed late. I always thought it was weird, I'd typically stay at least long enough to finish whatever thought I was working on, and sometimes later just because I had nothing important to get to. Eventually I became one of the guys to go to when you needed someone to stay late. I didn't mind, in fact I like being helpful. Looking back, I realized that I gave the company a lot of free work and didn't get anything for it. It seems obvious but important to realize from day one, you are setting expectations. A "good" manager will figure out pretty quickly which employees they can exploit and how.

No more than 2 years in a same company and always be interview ready. Keep regular contact with recruiters. There’s always a better opportunity.

This is exactly what my friend did. He earns double my salary even though I work in one of those big companies and do more than just development.

What area of the tech industry are you starting in? It would help to know so we could tailor the advice to you.

Never stop learning. Most important advice IMO.

Tech is a field that is constantly evolving, whether you're a developer or IT service desk, the tools you use today will probably be very different 5 or 10 years from now. Never get stuck in a rut, it'll burn you later in life. Remain curious and keep learning the new things coming out.

When interviewing, if a company gives you the "We work hard and we play hard" line, run. It actually means tons of unpaid overtime in exchange for some snacks and a broken ping-pong table.

you will end up bringing down production or make a however many tens of thousands of dollar mistake. Don't worry about it too much when it happens. That sort of thing doesn't usually get you fired the first time.

Be hard-working but loyalty will take you almost no where. Every 2 years you should start looking for a new job with better pay and less hats. If you are a year in and hate it just switch to somewhere new. I got 2% raises at jobs year to year but switching jobs for me got 20% - 40% more.

Read the damn code

Make things just complex enough that others don’t want to learn it but not so complex anyone can say it is too complex.

Also pick up tasks others don’t want to and make yourself hard to get rid of.

Then quit and get hired back as a consultant/contractor and work your own hours and how much you want to.

It can depend on the area you're going into, but things like continuous learning of new skills, as well as keeping up-to-date with the latest happenings in that field, are always good ones to do.

I’m looking to change careers into tech at 43. I’ve been a teacher my whole life but education is…just not a good job anymore. I’m very interested in data science and would love to end up working on climate modeling but I’m practical and understand that I should take what I can get. Anyone have some career wisdom they’d be willing to share?

All other comments in the post are gold.

Always stay relevant with skills and knowledge relevant to the market - one day you work for papa Google and everything is great, another day you'll get fired without you seeing it coming - job is not a family.

It's fun and games to master a skill/technology, but if there are no jobs for that, that is a red flag.

Generally it's important to keep the hobby-job balance, and to understand that sometimes your hobby specifically won't be your job, and that is OK because most of the people are like that.
