Discovering the Relevance of Words
Doyle Wesley Walls, my college poetry adviser, told us that if we write one poem each day for a year, and only one line from one poem is any good, we have done our job, and can begin the next poem.
Just keep in mind that whatever you write will lead to something better. Putting pen to paper, or fingers to keyboard, is the hardest part. Once you have achieved that goal, the rest will come naturally.
