Buddhist thoughts?

So, I have anger problems. Most people do, some worse than others. I think my friends that don't are lucky. I read books about this from time to time and to break things up a little bit, I want to share some. This one is about how to keep from getting mad at people that are close to you.

The moment of gratitude is a moment of enlightenment, of mindfulness, of intelligence. It is a manifestation from the depths of your consciousness. you have this understanding and insight in you but when you get angry, your gratitude and love do not seem to be there at all. You feel as if they never existed. For this reason you should write down those feelings of gratitude for a person so you can remember even when you are angry.
