The Power of a Positive Word – Proverbs 18:21

I know that comparison and a spirit of negativity are wrong, but it’s hard to just stop negative thought processes without having something else to turn to. I’ve thought a lot lately about the power of other’s words in my life, and I've been challenged to create a habit of speaking words of life and encouragement to others. Is it possible that searching for good things in others to compliment could help to build a more positive thought process in me?
