My greatest fear

When I’m a decrepit old man I don’t want to look back on my life and think: “Shit, I’ve been on the wrong track the whole time!” The problem is finding the right track without having to travel down it for twenty years before I know. That’s my greatest fear, and it’s a cruel one. It means I spend so much time trying new things that I don’t have time to follow through on my existing projects, because I’m afraid that I’ll waste too much time on something that won’t matter in my future.What’s your greatest fear?
