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

Little by little does the trick. – Aesop

What we call little things are merely the causes of great things; they are the beginning, the embryo, and it is the point of departure which, generally speaking, decides the whole future of an existence. One single black speck may be the beginning of a gangrene, of a storm, of a revolution. – Henri Frederic Amiel
