The longer it takes to fix a bug, the smaller the fix will be.
[I once spent two weeks finding a nasty bug in the Newton's OS, which was manifested by a mysterious and well-nigh irreproducible scheduler freeze. The fix was to swap two instructions in a trap handler.
You'll just have to take my word for this: I did the fix over then-Apple's Xmas holiday week off. You had to get very-high-level-manager approval to work during this week, because they paid triple. The fact they were paying me lots more money had nothing to do with how long it took to find the problem. Honest.]
Operating system people get no respect. All the hoopla and credit goes to the folks six APIs above your stuff, who move pixels around and make “ZIP-BOOM” noises while wasting cycles with horrible abandon. No one cares about the coal miners who pull those cycles out of the raw earth to begin with, it’s all about the actors using the light made by your coal.
Don’t forget that. Do, and you’ll wind up unhappy.
Bitterness equals 1 over the number of levels you are above the hardware. This, of course, makes hardware people infinitely bitter, which exactly matches observation.
