Life: Meditation. Zazen practice specifically. Redefined my values and "self" through introspection.

Programming: Realizing I'm not so great at it, moving towards programming as a hobby.

Yes. Zazen... If I could go back in time and give myself any advice, it would be the daily practice of silence.

So what have you changed your career for ? A job relating to programming, or something completely different ?

I agree with you.

And in 500 years I would imagine "human" being almost beyond comprehension to us now. Like, consciousness woven into spacetime at the subatomic level, crazy.
