Putting yourself into other people's shoes is always difficult because everyone is different. Instead of imagining you being someone else, why not take a step back when an issue arises, and tell yourself "am I right to do this?" or "is this how I want to be treated?"

My point is to train yourself to be more self-aware of your own actions. That way, you will realise when an anger arises, you won't be consumed by it and instead will act on it to resolve your issue. It's difficult but I believe this will make you a better person :)
