Whoever loves discipline loves knowledge, but he who hates correction is stupid. Proverbs 12:1
Have you ever had anyone point out your blind spots. Blind spots are those areas in your character that you personally cannot see, but others who see and hear you can point them out immediately.
Find someone who can see those blind spots and ask him/her to point them out to you. It might even be a “you tell me mine and I’ll tell you yours” scenario.
Now that you are aware of them, what will you do to correct them?
