Everyone's not the same. They don't have the same motivations. For the first decade of my job, I worked a steady, stable job that paid decently. It wasn't bad, but I was bored. Bored as in counting down the hours until the end of the work day each day, booking out all my vacation months in advance to the day.

I switched over to startups and have not looked back. Yeah, I work more, but I enjoy it a lot more. I can't do it forever, but the financial rewards have been better too, so I probably won't need to work to 65 like when I had the more stable, boring job.
