Start talking to yourself as you would a precious child. Talk to yourself like you are a child who deserves to be given love, honor, respect and dignity. Be polite with yourself. Treat yourself as kindly as you would the person you love best in this world. Stop worrying about your mistakes.
Mistakes are part of life.
We learn from our mistakes. Mistakes are the stepping stones to success. Rather than letting mistakes tarnish your self-esteem, allow your mistakes to enpower you.
