When aiming for the perfect shot, remember to keep sunlight in mind. Too little and you can't see the subject. Too much and one of two things happen. The first is that too much sunlight is directed into the camera's lens or on the subject and washes out the picture. The second is the person being photographed has to blink or close his eyes because of the massive amounts of sunlight coming into his eyes.
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.
