To be busy is to be happy?

So I'm busy. That's really all I can say right now. Between four classes (two of which include a ridiculous amount of lecture/lab time...), applying for programs here at Gustavus, applying for summer jobs, visiting my adopt-a-grandma, training for a half marathon, keeping up with my friends, and still maintaining a relationship with God, all I can say is I'm busy. And I am tired.
