I voted College, but I've really had three different callings. I felt called to military service during high school, then after completing my enlistment I felt a call to study music, and at the end of that time I was strongly called to pursue the ministry. I voted college, since that was the most profound of the three. A call is something internal and subjective. It may change, it may stay the same.

When Paul speaks of a calling, it is in the context of one's marital/servile status when they were converted to Christ. So calling there refers to the Gospel call, and that passage deals with how we should view our vocation/marital status in light of that.
