I’m not telling you to become a monk and move to a secluded place in the mountains. If you are practicing any religion, it is good to spend some time each day to pray and meditate on the teachings of your religion. Most religions teach a sense of well being and peace. This will help you keep a balanced perspective in life.
As a result, no matter what the external circumstances are, anger will not have a strong foothold in your life. If you do not have any affiliations to any religion, you can schedule some time each day to read a few pages of a motivational book and see if you can apply their ideas in your life. This practice will also enable you to see the big picture if and when anger threatens to cloud your judgment.
Benjamin Franklin once said, "Anger is never without a reason, but seldom a good one." Once we know the reason behind our anger (sometimes, it’s not our children’s bad behaviour which made us angry but rather, we have some unresolved anger from an incident at work/etc.), we can better deal with it.
We should strive to manage our anger effectively because our children do not deserve to be easy targets for us to unleash our anger. Think about it this way- you wouldn’t like it if you were at the receiving end, would you?
