Be patient, thoughtful and understanding. Anyone can be rude, but it takes real strength to be kind and polite.
Be persistent. Enduring strength does not come in an instant, but is steadily built over time.
Get in the habit of taking action. The strongest people are those who act while others only talk or wish.
Be humble. Put your focus on doing, rather than worrying about getting credit.
Be joyful. When you enjoy what you're doing, you are far more effective.
