Here's the interesting thing though which you see with both entrepreneurs and artists alike. Often, their best work was when they were constrained by resources
Here's a test: how many entrepreneurs you know who became successful (and rich) and then made a second project that also became as successful. It's fairly rare. And it's because success changes people's life. They are no longer (financially) dependent on the success of a project. They already have had money and success. Often the "chip on their shoulder" of "I'm going to show the world I can do it" is gone.
