How do I decide who I want to be?

I assure you , you are not .

I don't know what exact aspect of yourself you're trying to figure out but as someone who's been on a long self discovery journey, I'll leave you this advice:

Just live.

Stop stressing about it so much and just focus on the road ahead. See where life will lead you.

Sometimes it just takes time and patience.

I hope you find what you're looking for
