In life, people are trained to always create things that are almost perfectly even. While symmetry and perfection are things people look for, try and take pictures of your subject off center. Beware of auto-focus features that lock in to whatever is in the center of the lens. Use manual focus instead, and lock your focus before snapping the picture.
One of the key ways to take great photographs is to take lots and lots of them, so buy a large memory card that can hold them all. By increasing the size of the memory card that you use in your camera, you are increasing the number of photos that you can take before changing cards. A large card will also allow you to use RAW format so you can take advantage of the additional flexibility it offers.
When working around subjects that are moving a lot or are totally in action, you need to focus on capturing the moments by keeping your trigger down. These kinds of moments can not be recreated and there are no do-overs. Keep your eye on the areas at all times and keep shooting.
