Particularly for those working in highly demanding jobs: what drives you? What motivates you to work long hours and sacrifice free time to get ahead in your career?
I'm asking this because I realized I simply don't have the drive that I see in some friends who pursue IB/PE/big law. The first time I experienced a 70-hour week (very rare in my job), I was blown away by how physically and mentally taxing it was. Seriously, how do you guys do this repeatedly?
I know people will say it's the money, and while this may be true for some people, I don't think it's true for most. In my experience it has diminishing returns, and once you have enough to feel financially secure it stops being a major motivator and you look for fulfillment elsewhere.
