C.S. Lewis on Practice

I was reviewing some notes and rediscovered a quote from C.S. Lewis on the value of practice in writing:

What you want is practice, practice, practice. It doesn’t matter what we write…so long as we write continually as well as we can. I feel that every time I write a page either of prose or of verse, with real effort, even if it’s thrown into the fire the next minute, I am so much further on.
