Staying focused

[refnrev]

I know this happens to all of us from time to time, so I'd like some input from you. Some nights, because of family, work, personal, or other issues we know going into the game that we're going to be somewhat distracted and not up to 100% level. Having a real strong expectation on myself to do my best each night, this is hard for me. What do you do when the "tough" nights come and your mind wanders or you feel extra stressed because of the personal issues that have nothing to do with the game? How do you stay in the game and not doubt yourself or come down too hard on yourself on those nights? Thanks in advance for your comments.
