Slow down and try to set a good officiating pace. If you watch some of the better officials they have a very good pace to their officiating. If you slow down you have time to check some of the things mentioned in other posts. Less experience officials have a tendency to "pick up the pace" as a game gets in an up tempo mode or if things are getting a little hectic at the end of a hard fought contest. Keep a nice smooth tempo and this will help with your concentration in tight situations and give you time to think on the run.
