When we are not engaged in thinking about some specific problem, we usually spend about 95 percent of our time thinking about ourselves. Now, if we stop thinking about ourselves for a while and begin to think of other persons' good points, things will be quite different. One of the most neglected virtues is appreciation. Somehow, we neglect to praise our son or daughter when he or she brings home a good report card, and we fail to encourage our children when they first succeed in baking a cake or building a birdhouse. Nothing pleases children more than this kind of parental interest and approval. The next time you enjoy delicious food at a restaurant, send a word to the cook that it is excellently prepared,and when a tired salesperson shows you unusual politeness, please mention （it）. Every minister, every lecturer and every public speaker knows the discouragement of pouring himself or herself out to an audience and not receiving any appreciative comments. What applies to professionals applies doubly to workers in offices, shops and factories and our families and friends. In our interpersonal relations we should never forget that all our associates are human beings and hunger for appreciation. It is the legal tender that all souls enjoy. Try to be friendly and appreciative in your daily life, and you'll be surprised how that will change your life and the world.
