I have learned that if a person criticizes, judges, and underestimates others that if because of fears of failures and shames of his/her own.
Isn’t it time to stop worrying about what are saying or thinking about you? You are concerned about everyone, what they may think about you but for sure no one else is thinking about you as much as you are.
This concern is nothing but you. People do not care about you too much, they probably will not remember you later. If you do not mean anything for others, then why do you care about their thoughts about you.
Why do you take in shape according to their thoughts, criticisms, judgments. Why do you shape the one inside of you according to someone outside. Be yourself. Listen to the whisper of your heart, not the noise of others.
