A thought on point of view

I recently attended a training for an organization I volunteer for.  the speaker stated that happiness is basically due to our point of view.  Do you view the glass half full, half empty, or completely full?  I must admit, I can fall into any one of these categories on a given day.  Upon personal reflection, I agree that the way I look at a situation really will affect my attitude towards it.  She suggested that you should always try to think of what went right in the situation, even if it is only a small thing.  I have been trying this, and so far, so good!
