Three Good Things
Each day write down three good things that happened. They can be anything you feel good about or grateful for.
Even on a bad day there are normally some things that we can feel good about. Taking time to be grateful is not about ignoring the bad things - it just helps us focus our attention more on the positive, rather than dwell on the negative.
To get used to the idea, start by describing three good things that happened yesterday. Try to explain why each of the things were good.
