Becoming a 10X engineer (is it possible?)

Too Long; Didn't Read

According to the myth, there are engineers who can contribute 10X more than their peers. I don’t know whether this is possible or not, and I haven’t got a good metric for <a href="https://hackernoon.com/tagged/productivity" target="_blank">productivity</a> (right now, does anyone?!). I’d want to be one of the engineers who contributes 10x more so I need to find a way to measure and drive self-improvement.
