If you listen to constructive criticism, you will be at home among the wise. If you reject discipline, you only harm yourself; but if you listen to correction, you grow in understanding. (NLT) 

Proverbs 15:31-32

Meditation

To desire growth is to admit you are not where you want to be. To admit you are not where you want to be is to be self-critical. Why not get the opinions of others as well? This is constructive criticism. How do you handle criticism?
