What is the best possible way for a college student to juggle school, work, extracurricular act., volunteering, and social/family life all in one?

Take it from Clint: One of Clint Eastwood's great lines is from the 1970's movie Magnum Force. At the end of the movie, just after his character Dirty Harry has taken out the last bad guy, he says, "A man's got to know his limitations." This applies to women as well. Also, be sure to plan well ahead, use a calendar all the time, and keep a buffer of time in case something takes longer than expected.
