This was my experience. I had a relatively successful period as Startup founder, and was able to put away some retirement money. Then instead of doing another startup, I took a less stressful job for less money, and enjoyed my family time. As a founder I never really had a day off for 5 years. Even if I was "taking a vacation", my laptop was never always in a backpack within 20 feet from me for emergencies, and my mind was always focused on the consequences of failure. For me it was living in fear, even during success. Some people are more optimistic. They don't feel stress in the same way. I think that is a KEY ingredient in being a successful founder long term.
