Give with faith; do not give without faith. Give generously; give with modesty; give with respect; give with understanding.

The teacher sends the graduating student into life with this instruction. Share your time, your copy of this book and your attention warmly and humbly, with a real understanding of what the other person needs, and never as a lecture or with a price tag.
