--Be respectful and watch your language, or you might get thrown out!
--Listen to your coaches, because they know more than you and want to help you improve.
--Play fairly (except when the pitcher isn't watching, then by all means steal a base).
--Take turns; wait patiently; and cheer for your teammates when you're on the bench.
--Don't let your mind wander, lest you get hit by a foul ball or flying bat.
--Choose to feed your body in a way that will make you strong and healthy (and that won't land you in JAIL, duh!)
--Try your best, but keep in mind that even excellent hitters fail 2/3 of the time at the plate!
--Remember it's a long season, so even if today sucked, tomorrow's a brand new game. (And they average your stats, so the results look better...eventually.)
With apologies to Crash Davis, I will end with these profound words: "Sometimes you win, sometimes you lose, sometimes...it rains."
