Startups can be wonderful, but only if you (I) learn to enjoy the process. I'm glad you were able to find a way to enjoy your day to day and not continually defer enjoyment to the future!
I think that at the end of the day it comes down to being raw and completely honest with oneself. Most of us have the huge privilege of having a say in where our lives are going and my fear is that we entrepreneur tend (or have?) to have some rose-color glasses and always assume that we'll be part of that 10% that makes it.
If after a naked-honest conversation with yourself starups is for you, I wish you all the success in the world and a fulfilled life!
