The most destructive force we have is anger or it's close cousin hatred. In a moment of angry resolve we can tear down things and relationships that we have spent years building.
We have all seen it when someone gets so angry that they quit their job, quit their marriage or cut off a life-long friend. All in a moment and once done rarely can it be fixed. Especially when it comes to relationships.
Anger however can also be a constructive force to get us moving to do something we need to do. Tony Robbins; a well known self-help guru, got started when he got angry with himself and determined that he was no longer going to just coast through life. He just wasn't going to live as he had any longer.
The same intense emotion in both cases but with very different results.
What makes the difference?
It appears that destructive anger focuses on things and relationships outside of ourselves and constructive anger focuses on ourselves. So when we are angry with things, events, and relationships is the time we need to closely look at our perspective on what is causing our anger. We need to double check our actions to make sure we don't shoot ourselves in the foot.
