In order that a man may be happy, it is necessary that he should not only be capable of his work, but a good judge of his work.

What is really desired, under the name of riches, is essentially, power over men ... this power ... is in direct proportion to the poverty of the men over whom it is exercised, and in inverse proportion to the number of persons who are as rich as ourselves.

Pleasure comes through toil, and not by self indulgence and indolence. When one gets to love work, his life is a happy one.

He who can take no interest in what is small will take false interest in what is great.

Let every dawn of morning be to you as the beginning of life, and every setting sun be to you as its close: — then let every one of these short lives leave its sure record of some kindly thing done for others — some goodly strength or knowledge gained for yourselves.

Quality is never an accident. It is always the result of intelligent effort.

There is large difference between indolent impatience of labor and intellectual impatience of delay, large difference between leaving things unfinished because we have more to do or because we are satisfied with what we have done.
