Hate no one, no matter how much they've wronged you. Live humbly, no matter how wealthy you become. Think positively, no matter how hard life is. Give much, even if you've been given little. Keep in touch with the ones who have forgotten you, and forgive who has wronged you, and do not stop praying for the best for those you love.
A True friend is one who sees a fault, gives you advice and who defends you in your absence.
