Purpose in work? I don't even know the purpose of my life.
I love what I do and chose it when I had options, but sometimes I think I should switch to another sector to earn more money. Everything feels fuckedup sometimes, so I don't dwell on it too much.
Btw, 70 hours/week debate is nonsense, initiated by some random old-fashioned uncle who want to earn more billions. I would argue that people working at Infosys and Wipro, with the salaries they receive, should only work 15-20 hours a week and use the rest of their time to pursue their own interests or contribute to making the world a better place.
