The natural response of the human brain is to get angry at the person reporting the bug. Obviously this isn't very useful or logical. A better solution is to think about the problems reported, and decide whether it is a valid complaint or not. Many people automatically feel anger in situations like this, but you can train yourself out of it. It's essentially a kind of mindfulness: you just look at the situation intellectually and watch your emotions, rather than letting your emotions take control.

I would say the only logical time for feeling anger is when someone does something like raping or murdering a member of your family. Even then, anger is only useful in helping you formulate a plan of retaliation.

The best method for me was to reduce, as much as possible, my use of the words, "I hate XYZ."

For most of us, it's latter that causes the problem.

That is certainly a problem, but it isn't what I was referring to. I meant that hate and anger can lead to burnout (primarily fatigue and depression), if they are experienced excessively.

Acting out the anger may in fact lead to reduced chance of burnout, as it prevents the emotions from building up inside.

The side effects of a culture that stigmatizes anger or of acting on anger destructively, are that you experience it more.
