I kept my idea secret for years because I thought that as soon as someone else knew it, they would steal it, execute it, and become a billionaire while I'd be stuck in a cubicle forever. I thought I was so smart, but looking back, I can't believe I was so stupid. Once I started sharing my idea (only parts of it at first), I got instant feedback, what was good, what was stupid, how to improve it, who else to talk to, etc. You get the idea. My dream took wings and became my project only after I shared it with others.
