Any particular biographies on da Vinci you'd recommend? Particularly any that made him come across as a dabbler. I think I have a similar method of working on personal projects, and I'm curious to see how it worked in others.
Flights of the Mind is the best straight-up autobiography that I've read on him. The new Isaacson book is supposed to be great as well. It sounds silly, but How to Think Like Leonardo da Vinci is also surprisingly pretty decent.
