If your everyday life appears to be unworthy subject matter, do not complain to life. Complain to yourself. Lament that you are not poet enough to call up its wealth.

Above all, in the most silent hour of your night, ask yourself this: Must I write? Dig deep into yourself for a true answer. And if it should ring its assent, if you can confidently meet this serious question with a simple, "I must," then build your life upon it. It has become your necessity.
