Does anyone else feel like they're capable of much more?

Random question: does anyone else feel like they could get a lot more out of life, but struggle with actually turning their goals into a system they can stick to?

I've been working on something around this — basically, you answer a detailed questionnaire about your life, goals, habits and what you want to change, and I build a personal system around your situation instead of giving you some generic productivity plan.

I'm testing the first version with a few people right now, so I'm keeping it very small.

What's the biggest thing you'd want to get under control in your life right now?
