Here's a plan...

I place 3 coffee beans in my right hand pocket. If I have a negative thought I move a bean over to the left hand pocket. But, when I think of something positive - or how to change/solve the original problem - I move a bean back to the righthand pocket. The idea is that you end the day positively with the righthand pocket of beans. This encourages looking for positivity and challenging that which isn't.

I learned this at leadership school. It is far too easy - and we tend - to note the negative. The idea is to challenge that. To come up with plans, problem solve and generally look for the positive. I used to use this as a tool for management of people - ensuring that I also note and reward that which is done well.

This goes hand in hand with goal setting. It ensure that we don't take too much on; that our goals are reallistic. In this case they are very measurable and easily rewarded (which is a must)
