The highest reward for man's toil is not what he gets for it, but what he becomes by it. — John Ruskin. English writer and art critic (1819–1900)
...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.
In order that people may be happy in their work, these three things are needed: They must be fit for it. They must not do too much of it. And they must have a sense of success in it.
You will find that the mere resolve not to be useless, and the honest desire to help other people, will, in the quickest and delicatest ways, improve yourself.
What we think, or what we know, or what we believe is, in the end, of little consequence. The only consequence is what we do.
Say all you have to say in the fewest possible words, or your reader will be sure to skip them; and in the plainest possible words or he will certainly misunderstand them.
