Whether it's a letter, song lyrics, part of a novel, or instructions on how to fix a kitchen sink, it's writing. You keep your craft honed, you acquire the discipline to finish things. You turn into a self-taskmaster.

Writing ... is the great invention of the world.

Writing for other artists helped me figure out that magic you have to capture to make everyone connect with a song.

In writing songs I've learned as much from Cézanne as I have from Woody Guthrie.

There is nothing like writing to force you to think and get your thoughts straight.

All there is to writing is having ideas. To learn to write is to learn to have ideas.
