A way to practice is to start writing and to keep writing.
Write without stopping to worry, correct, or edit. Write for more than ten minutes without stopping. You will write some phrases you will really love. You will find it hard to throw them away.
Be ready to to throw them away because they probably won't fit the writing you end up with. If you don't come up with a whole new focus or angle, you will probably come up with a whole new subject.
Before you do throw away what have written do this: Read it and pick out your three or four best sentences. Then rewrite them. As you do so make, consider improvements you might make in them. Rewrite them and save them for a while.
