"Premature optimization" was happening a lot more in my head than on the screen. By that I mean I would waste time struggling to succinctly generalize a function instead of making something work the easy and ugly way FIRST. It is far easier to copy paste working code in 4 places and leave a nice comment on each about what could be probably consolidated... without actually doing the work at least until you come back to the code to make a minor change in those 4 places. Half the time you never come back, most other times you end up merging them within a week. And for outliers... good commenting saves the day.
