I would change confidence in people. Most people have a lack of confidence in being all that they truly were meant to be. I mean how many times have we heard our friends or loved ones talk about an idea that could really be life-saving or help someone in need. However, if you say to them, you should do that, they give every reason to believe that they are not able.
What a world this would be if everyone sought out to be confident in their own ideas. There would be no poverty, less sickness, and more love and compassion for our fellow-man.
We would not need to be envious because we know that we are confident within ourselves. We could start each day helping one another. Not worried about how someone would view us or re act to world problems.
