Why do you still work for others if money is just a number at this point? I worked for Google for a while and quit to do my own projects once I had enough money that I felt it didn't matter any more.

For me, interesting and fulfilling work is hardly work at all. 50 hours of fulfilling work essentially kills two birds with one stone (intellectually fulfilling, and pays my income), as opposed 40 hours at a job that I don't care for, but at least it's only 40 hours and pays alright, and then I have to try and sate my mind alongside everything else I want to do outside my working hours.

There's nothing worse than being stuck in a job where you're watch the clock, waiting for it to strike 5 PM.

Yeah, personally having a large chunk of the day be simple tedious tasks I don't have any control over makes me depressed and every day becomes a fight to keep the mental breakdown just out of reach. I envy people who can stay sane in such environments, makes life a lot easier.
