3) If you wish to become a musician, you seek help from the finest
musical instructor within reach. Just so in the greater art of living
effectively, seek help from those who have learned wisdom. As a rule,
your parents and your teachers are your best counsellors. They have
traveled the road before you, and have your highest interests at heart.
Listen to them. Don't make your life a wild experiment in blundering; it
doesn't pay.
4) Never regard age, even advanced age, as a joke. To do so blunts your
own sensibilities.
