“Nothing great was ever accomplished without enthusiasm,” according to Ralph Waldo Emerson.

Professors I know often remark that energetic responses make every class more stimulating. And as a former boss of scores of young people, I can tell you that Emerson is spot on.

There’s nothing better than to be able to make your life and the life of those around better, for free. Today, be the person about whom someone says, “that student just made my day.”
