Sometimes it happens that a programmer gets so annoyed or upset with something in a project that they sit down and implement a solution or solve a problem in one single multi-hour "rage-fueled" session.

Those are the best coding session. Headphones on, full focus and just code and code. Rage doesn't need to the motivation but "I'll show the others this can be done and ready in 6 hours, not 6 weeks" mantra works, too.

Everything. It gets shit done. Don't hate, just get it out on code because those MF can't.
