> I routinely come across developers who are the real deal: they’re conscientious and judicious in an unwavering way. They set a standard for themselves and do not compromise on it. Whether that’s a deliberate thing or whether they’re just built that way, it’s humbling to witness. If there’s a flaky test, they investigate it and fix it. If there’s a bug they spot in the wild, they make a ticket, and maybe even fix it then-and-there. If a new feature doesn’t gel well with the existing code, they refactor the code first rather than hacking the feature in. They’ll dive as far down the stack as necessary to get to the bottom of something. None of these things are necessary but great developers know that if they don’t address a problem early, and properly, it will only cost them more time in the long run. [... and more.]
This sounds like a great definition of not-lazy, and it does not mention long hours anywhere. My anecdotal experience is that I usually only have 20-35 not-lazy hours to give per week; any further hours per week are much less potent. Right now I'm working 24 hours per week and I think my employer is getting a great bargain: they don't have to pay me for hours that would likely be lazy.
