Always grateful and blessed. Be confident enough, to encourage confidence in others
Like Oprah Winfrey said "Be thankful for what you have; you’ll end up having more. If you concentrate on what you don’t have, you will never, ever have enough."
If you see no reason for giving thanks, the fault lies only in yourself. Be grateful in your own hearts. Gather courage to believe that you can succeed and also confidence comes with maturity, self-confidence is the best outfit.
You are good enough, smart enough, beautiful enough, and strong enough. Believe it and stop letting insecurities ruin your life.
