H - Head, Hands, Heart, and Health. I hate to go all 4H on here, but I have found that the ideas in the 4H pledge are a good model of a camp counselor to keep in mind:
"...my HEAD to clearer thinking
my HEART to greater loyalty
my HANDS to larger service
and my HEALTH to better living..."

If you're always thinking before acting, thinking about the impact of your words and actions, you should be an excellent camp staffer. Your heart to be compassionate to children when they need you, and to your fellow staffers too. Yours hands to help guide, "greater service" by helping others even when not asked to. And health needs to be a priority for you just as much as campers! Please take care of yourselves!
