Action is a great restorer and builder of confidence. Inaction is not only the result, but the cause, of fear. Perhaps the action you take will be successful; perhaps different action or adjustments will have to follow. But any action is better than no action at all.
Fear can infect us early in life until eventually it cuts a deep groove of apprehension in all our thinking. To counteract it, let faith, hope and courage enter your thinking. Fear is strong, but faith is stronger yet.
Every person, if he is to have mental health and live successfully, must move away from past failures and mistakes and go forward without letting them be a weight upon him. The art of forgetting is absolutely necessary.
