«The world isn’t a place where you can just have an idea and sell it for millions; ideas are a dime a dozen. The value is in the execution, and the more you can control that execution, and rein in spending so that it can be directed efficiently, the more likely that your execution will be successful. This means doing a lot of things on your own, hiring experts when necessary to do things of limited scope, and devoting your energy to just the things that will move you forward.»
