How do you “make sure” you have purpose though? If everyone knew how to do that, I think everyone would be awesome.
Well it's a moving target. At 20 it's different than 30 or 40. You gotta do stuff that gives you self esteem and personal value while making you improve. It's the things that you enjoy that also develop you in some way. For me it was drawing, then guitar, then martial arts, then boxing, and so on...school, a career, a wife, kids are all "meaning things" but are not just for me, but other people too. You should never only have one thing to go to. You should have a couple things because they round you out.
I dunno, just go out and experience things that make you realize new and better things about yourself and life in general.
You can't be given meaning as authentically as you can have someone discover it in relation to who they are at a given time in their life.
People that don't believe in themselves, or have low self-efficacy can be afraid to strike out into new things/frontiers. It's hard to be awesome (your word) if you don't believe in your ability to figure things out.
You can't have the pursuit of meaning without desire and conviction.
You can't act these things out without time, opportunity, freedom, and a reasonable means (money, for example, to pay for guitar lessons and a guitar).
