Diller’s process for navigating the unknown isn't about brilliance but relentless iteration. He describes it as taking "one dumb step" at a time, bouncing off the walls of bad ideas and mistakes, and course-correcting. This embraces looking foolish as a prerequisite for finding the right path.

Bootstrapping is often a capital constraint that limits a founder's full potential. Conversely, venture capital removes this constraint, acting as a forcing function that immediately reveals a founder's true capabilities in recruiting, product, and fundraising.
