Keep it short and sweet. People blame today's fast-paced tv and movies for our short attention spans, but the principle's always been true.

A few interesting remarks, every now and then, will be more helpful than to give all the instruction at once.

Meet them where they are. He reached us where we were, that He might lift us up. Treat them as you'd want to be treated. When youthful disciples are overcome by temptation, let not those older in experience deal with them harshly, or regard their efforts with indifference. Remember that you yourselves have often shown but little strength to resist the temptor's power.
