This too shall pass. Enjoy what you can, but don't get attached to it. You can even become deeply involved in something or with someone, but always be emotionally and mentally prepared for the day when it or they are no more. Expect it.

Treat others how you would like to be treated. Adress others the way you want to be adressed.

I don't believe in free will meaning that what ever you did you could not have done otherwise. We live in a deterministic universe and all events are part of a causal chain

I think calling anything I think or hold to possibly be true a "belief" is not quite accurate. I don't really have faith or anything like that. I believe things that can be proven to be real, and I have ideas that may count as philosophy but without a belief that it is correct or not. Like, I think it's entirely possible for an afterlife of some such to exist. If matter and energy can not be destroyed, only transformed, and our consciousness is a form of energy, then maybe we still retain consciousness after death on a different level of existence which could be attributed to Heaven or Hell or any other religious idea of an afterlife. On the other side of the same possibility, I don't think a God is possible. God is either simply a convenient name for the randomness of the universe, or was an alien race not much different than us, but way, way more advanced technologically.

Is that really philosophical, though?

Optimistic nihilism has always been a favorite. While there may be a purpose to existence, there is no concrete evidence of it. But if indeed life has no meaning, that's not a big deal, because humans are creative and can create our own.

1. Humanity is living in an (almost) endless painful cycle of civilisations rising, prospering and falling, like a phoenix rising from its ashes, only to burn again. No civilisation, nation, or idea can escape. Some might be able to avoid destruction for longer than others, but they will eventually meet their end.

2. Death is and should be inevitable, and it's a good thing. I have gotten over the fear of dying when I was eight, yet so many people, (way too many of them are adults) seem to treat death as a sensitive and even taboo topic.
   I find the thought that I'll most likely be able to rest peacefully either in a state of non-existence or some sort of afterlife to be calming. I tend to think that the acknowledgment of our own mortality is the only thing that makes us truly enjoy life, as we know it won't last forever. This is the reason why people talking about technology that could make immortal people without thinking about the downsides enough really concerns me. Humans are supposed to be born, to live and to die.

3. If we want to define whether an action is immoral or moral, then as a rule of thumb, it is moral as long as it doesn't hurt anyone. (yes, this includes non-human animals) There are a lot of exceptions of course.

4. Humans are not superior to other animals. The reason I think that, in general, killing another human is worse than killing another animal is not that human lives matter more than lives of other animals, but instead that you shouldn't kill your own species.

I think as renewable energy gets cheaper and we move away from scarcity in society, we will stop looking at ourselves as brands. Instead, personal conduct, or the appearance of such will play a much larger part in our public lives and place in society. This will provide a lot of privacy issues.
