When a man feels throbbing within him the power to do what he undertakes as well as it can possibly be done, and all of his faculties say ''amen'' to what he is doing, and give their unqualified approval to his efforts, -- this is happiness, this is success.

It is those who have this imperative demand for the best in their natures, and who will accept nothing short of it, that holds the banners of progress, that set the standards, the ideals, for others.

Doing common things uncommonly well.

Put the uncommon effort into the common task... make it large by doing it in a great way.

There is an infinite difference between a little wrong and just right, between fairly good and the best, between mediocrity and superiority...

The greatest thing a man can do in this world is to make the most possible out of the stuff that has been given him. This is success, and there is no other.

Superiority -- doing things a little better than anybody else can do them.

The quality of your work, in the long run, is the deciding factor on how much your services are valued by the world.

When we are sure that we are on the right road there is no need to plan our journey too far ahead. No need to burden ourselves with doubts and fears as to the obstacles that may bar our progress. We cannot take more than one step at a time.

Obstacles will look large or small to you according to whether you are large or small.
