Everything that happens in my day is a transaction between the external world and my internal world. Everything is raw material. Everything is relevant. Everything is usable. Everything feeds into my creativity. But without proper preparation, I cannot see it, retain it, and use it. Without the time and effort invested in getting ready to create, you can be hit by a thunderbolt and it'll just leave you stunned.
