Only Intrinsic Motivation Lasts

Why I quit a $500K job at Amazon to work for myself

"What kind of work would I do if I had to do it forever? Not something that I did until I reached some milestone (an exit), but something that I would consider satisfactory if I continued to do it until I’m 80. What is out there that I could do that would make me excited waking up every day for the next 45 years that could also earn me enough money to cover my expenses? Is that too unambitious? I don’t think so. Because there are two types of drivers that get me out of bed in the morning."

"The things that don’t wear off are those that I’ve been doing since I was a kid, when nothing was forcing me to do them. Things such as writing code, selling my creations, charting my own path, calling it like I saw it. I know my strengths, and I know what motivates me, so why not do this all the time?"
