I'm that guy who joins your project and reformats your code for consistency, and who relentless refactors your code into something readable and DRY.
I've spent a great deal of time learning how to set manageable goals for myself on a near daily basis. I'm also learning how to let my expectations for others be set by others (versus me setting very high standards for them). So, I can see a bit of myself in this article. I often wish I cared a little less. It seems like an easier life.
