I remember when I was 14 and cried myself to sleep since I was in a panic about what to do in life, I realised I had so many options from going into mathematics, medicine, engineering or music but probably never being able to be great in more than one at a time. I felt I had to choose.

I'm 35 now and I still get that feeling sometime, but I have changed focus in my career often enough to know that you can have small successes and appreciate them.
