Also, be totally familiar with all your tools and equipment. Use them routinely and practice seldom used skills. We tend to "fight like we train".
I tell this to the kids I work with in martial arts...if you practice weak, your response will be weak...especially when you don't have to to think...just respond. Practice like your life depends on it...because some day, it just might.
