Half empty

If you see the glass half empty, there are several natural reactions you are likely to have – feeling bad about what is missing, resenting what is missing, getting defensive about what isn’t there. These reactions make it harder to enjoy what is in your glass. On the other hand, when you see your glass half full, there is a natural tendency to value what is in your glass, thus increasing the chances of enjoying it. This reaction naturally enhances your pleasure with what is in your glass.
