Yogi Berra, former New York Yankees baseball player, demonstrated the linguistic gymnastics that earned him eight entries in Bartlett's Familiar Quotations when he addressed graduates at Montclair State University:

First, never give up, because it ain't over 'til it's over.

Second, when you come to a fork in the road, take it.

Third, don't always follow the crowd. Nobody goes there anymore. It's too crowded.

Fourth, stay alert. You can observe a lot just by watching.

Fifth, and last, remember that whatever you do in your life, 90 percent of it is half mental.
