Many people are depressed because they spend too much time thinking about the evil that men have done to them. If you count your grievances what do you expect if not more grievances? Forget your your grievances. If you must count anything, count your blessings. What you appreciate increases in value. For instance, if you have a house and you are told that it has appreciated that means the value of the house has increased. The problem with most people is that they appreciate their grievances more than their blessings and their grievances increase as a result. In the military, any damage that is above the targeted destruction is called a collateral damage. Why should you suffer from collateral damage by thinking about a grievance long after the injury has been done? Why not go for collateral blessings by thinking about your blessings long after you have been blessed?
