In order to commit to doing a ridiculous amount of work to bring an idea to reality, one must believe deeply that there's a realistic chance the venture will lead to obscene wealth, fame, magazine covers, and a 60 Minutes interview. Believing this, people vastly overestimate the risk that someone else will see how brilliant the idea is and run with it. It goes with the territory.

Just because you're paranoid doesn't constitute proof that they are out to get you.
