When you do eventually get to the shooting (after wearing yourself out skating of course
), make sure you practice a variety of different shots. A hard slapper might look impressive, but you're shooting yourself in the foot if it's the only thing you focus on. The wrist shot and backhand are absolutely devastating if you can master them.
Edit: also work on keeping your head up (this pairs nicely with stickhandling and passing). Good peripheral vision is critical to a long and fortuitous hockey career.
