You probably want to ignore the advice about snapping your wrist. People think you can draw the cueball further with a wrist snap, but that is bull. I have watched top players draw the cueball for years looking at their techniques and I have yet to see any top player use a wrist snap when drawing the ball long distance. An extremely loose wrist, which is required so you can snap it, destroys your timing, and without good timing, you won't be able to draw the ball. Keeping your wrist still but NOT TIGHT like you are tensing it, just keep it relaxed but still. Don't let it flop around during your stroke.
