Always use positive words, and never use negative or evil words. Cultivate good thoughts, not bad thoughts. Make sure your intentions are constructive intentions. Never be jealous; be grateful. Be tolerant, peaceful, and honest instead of vengeful. Always be compassionate, never proud and arrogant. Praise God, because God is the Deserving One. You need these in your life. If you can teach yourself to follow these suggestions, you will have a very good life.
