Here is an example: someone submits an email to your customer support. The email starts with "your software is full of bugs". They go on to list all the problems they've had. 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.
