It can be helpful simply to make a written or mental list of the things you do each day. Then give yourself a mental credit for each of them, however small. This will help you focus on what you have done instead of what you havent gotten around to do. It may sound simplistic, but it works. – David D. Burns

The happiness of life is made up of minute fractions — the little soon forgotten charities of a kiss or smile, a kind look, a heartfelt compliment, and the countless infinitesimal of pleasurable and genial feeling. – Samuel Taylor Coleridge
