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)
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?
