LOL - good coders are RELENTLESS workers (well, like all artists really). Part of that is loving what you do--and if you do, it's easy to put in the hours.

The corollary of course is that if you don't love it (be it coding or any other endeavor) then it's just a "job" -- and you'll also then never be really good at it.

And unfortunately that describes so many--working 9-5 at something they don't love, and being only average at best.
