Don't be afraid to fail. The greatest failure of all is failure to act when action is needed. Use the information that you've acquired in the past through the experiences you've had and act with self-control - but act.
Be true to yourself, help others, make each day your masterpiece, make friendship a fine art, drink deeply from good books - especially the Bible, build a shelter against a rainy day, give thanks for your blessings and pray for guidance every day.
