How many times have we all heard the following mantra?

I work smarter, not harder.

Isn't it seductive? As long as we are smart, we don't have to work as hard, right? After all, who really wants to work harder?

Well, as it turns out you can work both smarter and harder, and you probably should, too, if you want to get any better at what you do. Especially if you're trying to keep up with John Carmack.
