Isn't it great to know that trying to change someone is a waste of time? The very thought of wanting to change someone is saying they're not good enough as they are, and that thought comes from judgment and disapproval. That's not a thought of appreciation or love, and it can only bring separation between you and that person.
Look for the good in people to have more of it appear. As you look for the good things in a person, you will be amazed, stunned, and wowed at what happens! If you don't want to look for the good, then don't look at all..
