From my coworker, Igor:

It is too late for me. I had my formula. Man who clean cow's crap all his life afraid mostly that cow will die.

This was his reaction to Paul Graham's essay, How to Do What You Love.  A short excerpt, a few paragraphs, of the excellent essay:

To do something well you have to like it. That idea is not exactly novel. We've got it down to four words: "Do what you love." But it's not enough just to tell people that. Doing what you love is complicated.

The very idea is foreign to what most of us learn as kids. When I was a kid, it seemed as if work and fun were opposites by definition. Life had two states: some of the time adults were making you do things, and that was called work; the rest of the time you could do what you wanted, and that was called playing. Occasionally the things adults made you do were fun, just as, occasionally, playing wasn't-- for example, if you fell and hurt yourself. But except for these few anomalous cases, work was pretty much defined as not-fun.

...

It's hard to find work you love; it must be, if so few do. So don't underestimate this task. And don't feel bad if you haven't succeeded yet. In fact, if you admit to yourself that you're discontented, you're a step ahead of most people, who are still in denial. If you're surrounded by colleagues who claim to enjoy work that you find contemptible, odds are they're lying to themselves. Not necessarily, but probably.

I think this is a must read for anyone between the ages of 16 and 30; it's a revelation to why many of the youth today are mired in apathy and seemingly dragged down by the weight of responsibility.
