You have trouble figuring that ONE thing you have to do with your life.
You have a ton of interests but are living in a world where we need to "specialize".
I recently stumbled upon a book titled "How to Be Everything: A Guide for Those Who (Still) Don't Know What They Want to Be When They Grow Up" by Emilie Wapnick.
The gist of the book is this. You don't have to choose just one thing.
There is room in your life for the things that move you.
