I would have some choice words for my past self if given an opportunity to say anything to them.

Buy stock in Apple, and pick up any stock you can in an little startup called Tesla when it is founded.

That Bitcoin thing that will come along? Yeah, it's dumb, just mine a couple of Bitcoin for the fun of it, put it in a safe place and document everything you need to know to access it, then forget about it for about a decade.

Houses, they're expensive right? Ha. Ok. Buy one anyways. Like, as soon as you can. Just do it.

Don't buy that, or that, or that, or that, or that either. It will only lead you down a path towards lifelong debt. Just don't do it man.

Oh, and the girl isn't worth it, stay living at home for a while longer, don't get kicked out because of some broad. Dump her, and go spend your money on a house.

Go play this Geo game in (nearby city), you'll meet an awesome girl you'll want to marry, on that app. Just trust me on that one.
