This essay is a great read. My favorite quotes from it:
That’s where the upper-middle class tradition comes from. Just as houses all over America are full of chairs that are, without the owners even knowing it, nth-degree imitations of chairs designed 250 years ago for French kings, conventional attitudes about work are, without the owners even knowing it, nth-degree imitations of the attitudes of people who’ve done great things.
That’s what leads people to try to write novels, for example. They like reading novels. They notice that people who write them win Nobel prizes. What could be more wonderful, they think, than to be a novelist? But liking the idea of being a novelist is not enough; you have to like the actual work of novel-writing if you’re going to be good at it; you have to like making up elaborate lies.
Whichever route you take, expect a struggle. Finding work you love is very difficult. Most people fail. Even if you succeed, it’s rare to be free to work on what you want till your thirties or forties. But if you have the destination in sight you’ll be more likely to arrive at it.
