I used to feel like that when I was younger. Now many years later I haven't accomplished the goals I set years back, but I feel happy. I spend my days working on interesting problems and feel I'm learning so much all the time.

I'd say the key is concentrating on what you're doing that makes you happy. If coding is your passion and you're coding 50 hours a week now, you'd probably do the same if you were rich and famous. Or maybe you wouldn't have so much time for coding with everything else coming your way.
