Freewriting is the easiest way to get words on paper and the best all-around practice in writing that I know. To do a freewriting exercise, simply force yourself to write without stopping for ten minutes. Sometimes you will produce good writing, but that's not the goal. Sometimes you will produce garbage, but that's not the goal either. You may stay on one topic, you may flip repeatedly from one to another: it doesn't matter. Sometimes you will produce a good record of your stream of consciousness, but often you can't keep up. Speed is not the goal, though sometimes the process revs you up. If you can't think of anything to write, write about how that feels or repeat over and over "I have nothing to write" or "Nonsense" or "No." If you get stuck in the middle of a sentence or thought, just repeat the last word or phrase till something comes along. The only point is to keep writing. Or rather, that's the first point. For there are lots of goals of freewriting, but they are best served if, while you are doing it, you accept this single, simple, mechanical goal of simply not stopping. When you produce an exciting piece of writing, it doesn't mean you did it better than the time before when you wrote one sentence over and over for ten minutes. Both times you freewrote perfectly. The goal of freewriting is in the process, not the product.
