Yes, this is very similar to the advice Paul Graham gives when talking about "ramen profitability", because it takes time for people to create things of value - whether it's a startup or the next great Harry Potter story. In fact J.K. Rowling talked about her mad rush to just finish the first Potter book before returning to full time employment as a teacher, when there would be no time to write. It's interesting to me the people who tend to create the higher value things, artists in one form or another, are usually fairly poor. Not sure how many rich people create new things of value, or maybe it's just because there are disproportionately more poor people than wealthy people.
