It was not till I was in college that the idea of work finally broke free from the idea of making a living. Then the important question became not how to make money, but what to work on. Ideally these coincided, but some spectacular boundary cases (like Einstein in the patent office) proved they weren’t identical.

The rule about doing what you love assumes a certain length of time

The definition of work was now to make some original contribution to the world, and in the process not to starve. But after the habit of so many years my idea of work still included a large component of pain. Work still seemed to require discipline, because only hard problems yielded grand results, and hard problems couldn’t literally be fun. Surely one had to force oneself to work on them.

If you think something’s supposed to hurt, you’re less likely to notice if you’re doing it wrong. That about sums up my experience of graduate school.

How much are you supposed to like what you do? Unless you know that, you don’t know when to stop searching. And if, like most people, you underestimate it, you’ll tend to stop searching too early. You’ll end up doing something chosen for you by your parents, or the desire to make money, or prestige-or sheer inertia.

Even Einstein probably had moments when he wanted to have a cup of coffee, but told himself he ought to finish what he was sugar daddy la working on first.

It used to perplex me when I read about people who liked what they did so much that there was nothing they’d rather do. There didn’t seem to be any sort of work I liked that much. If I had a choice of (a) spending the next hour working on something or (b) be teleported to Rome and spend the next hour wandering about, was there any sort of work I’d prefer? Honestly, no.

It doesn’t mean, do what will make you happiest this second, but what will make you happiest over some longer period, like a week or a month.

Unproductive pleasures pall eventually. After a while you get tired of lying on the beach. If you want to stay happy, you have to do something.

As a lower bound, you have to like your work more than any unproductive pleasure. You have to like what you do enough that the concept of “spare time” seems mistaken. Which is not to say you have to spend all your time working. You can only work so much before you get tired and start to screw up. Then you want to do something else-even something mindless. But you don’t regard this time as the prize and the time you spend working as the pain you endure to earn it.

I put the lower bound there for practical reasons. If your work is not your favorite thing to do, you’ll have terrible problems with procrastination. You’ll have to force yourself to work, and when you resort to that the results are distinctly inferior.

But the fact is, almost anyone would rather, at any given moment, float about in the Carribbean, or have sex, or eat some delicious food, than work on hard problems

To be happy I think you have to be doing something you not only enjoy, but admire. You have to be able to say, at the end, wow, that’s pretty cool. This doesn’t mean you have to make something. If you learn how to hang glide, or to speak a foreign language fluently, that will be enough to make you say, for a while at least, wow, that’s pretty cool. What there has to be is a test.
