Well, first off, if you have digital products like ebooks, it's not as if people will just stop buying them. He may not write more books but I imagine Nathan will still make a decent amount of monthly revenue with little intervention. But selling actual software requires a lot more maintenance than ebooks. Also, some people (myself included) are a lot more susceptible to parkinson's law with regards to money. I don't have an "enough money" number. I'm not greedy but if I can maximize my income while working a healthy amount, I'm going to do it. (All my kids are in school anyway). If I want to take extended time off and embark on adventures with my family, I'm going to do it.
