I know people who can just solve problems. If it takes me all day to solve something, I'll reach out to Ken and he'll say "oh, check this setting. It is probably X". Dennis has seen so many problems, he knows how I've tried to solve them and the solutions before I've finished describing what is going on.
If these guys solve something in 48 minutes that take others 8 hours, they are 10Xers.
But they are more than being "10x productive"; they solve problems that would otherwise not be solved. They get stuff done that other people would lose patience with before it is ever solved. And the best part: it isn't even HARD for them. When those guys rock, they do it with ease, they do it for FUN.
Sometimes I am a 10x programmer. Sometimes I spend 48 minutes solving a problem others work on all day before deciding it isn't possible. My goal isn't to "be a 10x programmer", my goal is to be "10x more often today than I was yesterday".
