It reminded me (I need be reminded for the umpteenth time) that it's OK to start before you're ready.
The Dorm Room Mindset reminded me that making progress is more important than getting it perfect. It reminded me that success is the progressive realization of a worthy ideal.
The process of building things looks different today than it did, say, 10 years ago. Back then it was harder to go to market. Today it's easier than ever to go to market with a concept only and gain feedback, or even gain money, using just an idea in order to go further in the process of whatever we're building.
Anyone with an idea and interest can contribute small amounts of energy that may add up to a lot. We can make it a hobby to chip away at building something meaningful over time.
Contrary to what I might often think, I really don't need money to test a new idea.
Good enough sometimes is.
