My experience is the most impressive people are significantly less likely to quit early. If they where doing a lot of interesting things in their free time they either become engaged with interesting projects at work or put in a solid work week and then go home to have fun with their own projects.

Albert Einstein for example worked for several years as a patent examiner while developing special relativity. Sure his contemporary physicists mostly worked in academia, but teaching is as unrelated to research as everything else yet they still did it.

Sometimes having a light day job gives you more energy for your personal projects you care a lot more about at night :)
