Our enemy is not lack of preparation; it's not the difficulty of the project, or the state of the marketplace or the emptiness of our bank account. The enemy is resistance. The enemy is our chattering brain, which, if we give it so much as a nanosecond, will start producing excuses, alibis, transparent self-justifications and a million reasons why he can't/shouldn't/won't do what we know we need to do. Start before you're ready.
