A growing thing whose stages of growth always went unnoticed ...

He does a lot of things that go unnoticed,

Nothing goes unnoticed. Someone is always around to spill the beans.

If your advertising goes unnoticed, everything else is academic.

The most solid advice for a writer is this, I think: Try to learn to breathe deeply, really to taste food when you eat, and when you sleep really to sleep. Try as much as possible to be wholly alive with all your might, and when you laugh, laugh like hell. And when you get angry, get good and angry. Try to be alive. You will be dead soon enough.

You must remember always to give, of everything you have. You must give foolishly even. You must be extravagant. You must give to all who come into your life. Then nothing and no one shall have power to cheat you of anything, for if you give to a thief, he cannot steal from you, and he himself is then no longer a thief. And the more you give, the more you will have to give.
