" Alertness and courage are life's shield."
"As you strive to reach your personal best,
alertness will make the task much easier.
Be observing constantly,
quick to spot a weakness and correct it or use it,
as the case may warrant."
~Coach John Wooden
This means constantly observing what's going on around you. It means keeping an open mind. It means always being eager to learn and improve. It means to "look alive," and "stay-awake."
Obviously this is important during a game so that you don't look rediculous. You have to know what's going on in the game in order to call appropriate chants, stop chants when it's the right time to stop, key-into what gets the fans to respond, the needs of your squadmates, etc. These are skills that get built with experience.
Obviously it's important while stunting to stay focused, to keep your eye on the flier and make sure that she never hits the ground.
But perhaps most importantly, it's important when it comes to self-awareness. Were you AWARE that your grades were slipping? Were you AWARE that adults were watching when you were smooching your beau? Were you AWARE that preschoolers were around when you were kussing?
