Jad, you just need to relax and enjoy life a little man. Eat some ass, get high and find a hobby that interest you. If you don't know what you like, try different things and you'll know if you like something or not. Don't overthink it. Life is a lot more simpler than you think or it can be difficult if you make it to be.
I already do those things (wrestling, rugby, go out with my boys almost everyday) but I'm also interested in stuff like philosophy and history because thats what my dad grew up teaching me. And yea you are right that life can be simple or difficult depending on what you make it out to be.
