Breaking old habits begin with realizing the emotion or action is not profitable. Realize what motivates you to feel the way you did and pay attention to your perception concerning what people say and do around you. This does not mean become defensive, it means to pay attention to you, your thoughts, and actions. The change you seek is often times waiting on you. On the flip side keep a balance, constructive criticism is good but know who will give you honest criticism to help you grow and not tare you down. Other peoples opinion of you is not God’s opinion of you.
