Money's nice, but not hating your life is nicer. I'd make a rubbish Sisyphus.
Startup life isn’t working on what I want, it’s agile firefight every sprint. Corporate life wasn’t working when I wanted, it was plowing through the day unproductive and unmotivated.
Early in my career, I wanted experience with as many parts of the business as possible, I wanted to work on really hard problems and build really cool stuff, and I could take risks.. I was young and perfectly comfortable with a bad work/life balance because I had no other commitments.
At this stage in my career, I value stability and work/life balance much more, and while I am still looking to solve hard problems, it's not at the urgent pace that startups demand, and how I define "hard problem" has changed too.
