There's another sense of "not everyone can do work they love" that's all too true, however. One has to make a living, and it's hard to get paid for doing work you love. There are two routes to that destination:
The organic route: as you become more eminent, gradually to increase the parts of your job that you like at the expense of those you don't.
The two-job route: to work at things you don't like to get money to work on things you do.
