Do what nobody else can do for you. Omit to do anything else.
Nothing goes by luck in composition. It allows of no tricks. The best you can write will be the best you are.
If you can speak what you will never hear, if you can write what you will never read, you have done rare things.
If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them.
In human intercourse the tragedy begins, not when there is misunderstanding about words, but when silence is not understood.
