Purpose, passion, and preaching

Preachers, this ought to speak to many of us: a college journalism teacher writes on what's really involved in following one's passion:

Forget about Rick Warren and his rigid “Purpose-Driven Life.”

Take a lesson from deadline writers, who often must accept an assignment before having every detail worked out. If journalists can train themselves to take a leap of faith every time they are dispatched into the field, so can we all.

Good point.
