What is a Batcave? It's a home base. The intentional space you use to create. Organization is important. Pete talks about how Robert Rodriguez likes to create at the speed of thought. We talk about Casey Neistat's studio that is purpose-built for creating an environment for getting work done. Building a Batcave is something that you get to apply creativity toward, for the sake of creativity. Build a space that is for YOU (or your team/family). Pete's been collecting artifacts to remind him why he's in the game. That's an important thing to have in your Batcave. Your Batcave should be aesthetically pleasing, but also practical and useful. Remember, you're building it for you.
