In addition to this, gripping with your knees will lock your hips, and you will not be able to move them with your horse correctly. Keep your legs relaxed. =]
Think of it like your hips are a cup, and you are scooping up a cup of water with every canter stride. Down, forward, up, back, down, forward, up, back. Trying saying that to yourself, it's helped me out. Also, try and get someone to lunge you so that you can focus on feeling the canter without worrying about steering your horse. =]
