That's exactly why I mentioned the stylus.(it even comes with a booklet with instructions I believe)

If you don't feel like checking out that pick, just focus for a while on only using the very edge of the pick, and make sure your arm is relaxed at all times.
It's easier to get a good 'hit' on a string when you hit it hard. But if you practise on hitting the string perfectly with the edge of the pick each time, you'll need less power when picking. You'll end up playing faster and more relaxed.
