I think there's a couple of essential maker reads:    - The Lean Startup: the entire maker movement is based on it.  - Business Model Generation: it's generally a pretty useful book for figuring out how to monetize something!  - Hooked: if you're building a habit-based book, this is a must.  - Essentialism: do you struggle with trying to do too much at once? This is your book.    What are some essentials I missed? Discuss.
