But that's a separate issue from having billions. You can work 70 hours a week and still have troubles with money (like me, but it's my own fault, most of my friends envy the amount I earn, but I spend it all on maintaining home and mortgage, but maybe this year I will replace that 8yr old laptop). Or you can have billions from working two years and then just resting the rest of your life.

If you hate your job. If you love it, it's play time.
