This is a brilliant summary. I recall following Michael Lynch's journey while he built TinyPilot (https://tinypilotkvm.com/). I was blown away by how hard he grinded to build that business. It just never let up -- the competition. As successful as he was, the exit value seemed like a let down (I say that as a fan!). So, I agree: "Draw circle" by far the hardest part. For "rest of owl", just hire other (grind-ier/thirst-ier) people to do it for you!
