Words indeed have power. My favourite quotations on words:
1. "Words are free. It's how you use them that may cost you."
2. "Be mindful when it comes to your words. A string of some that don't mean much to you, may stick with someone else for a lifetime."
3. "Two hearts in love need no words."
4. "Integrity is the most valuable and respected quality of leadership. Always keep your word."
5. "Words are all we have."
6. "Don't mix bad words with your bad mood. You'll have many opportunities to change a mood, but you'll never get the opportunity to replace the words you spoke."
