What do you lose yourself in as an adult?

That's a hard question for me to answer these days. But I feel that if I could answer that question,my searching would end.

I think I gave up my passions and what mattered most to me to become an adult. Only to realize that the things that will keep me sane as an adult are those things that I gave up.

So knowing that now, how do I reclaim who I am and what I desire?
