My life is essentially:

• Don't have huge financial and career expectations.

• Be healthy and self-improve.

• For fucks sake don't get into debt.

• Do not commit crime.

• At least try to work for good of society (or just not make things worse I guess).

And that's enough for me, and I recommend at least following first 3 points for good enough life without much stress (and last 2 if you're not an asshole).
