I have been there. I recommend the book: "Refuse to Choose!" by Barbara Sher. Short intro: https://www.getmotivation.com/motivationblog/2017/04/barbara... In short: get over the feeling of guilt first, then organize your multitudes of interests.
It's really scary reading those quotes, I will definitely have a look at the book.
Like the author says, I have spent most of my life wishing I was a Diver. That I could focus and become great at one thing.
