Fear is a good thing. It keeps us safe and out of trouble most of the time. May I suggest addressing focusing on how to process and manage fear instead?
Teaching our children how to face our fears and respect them may be a better approach. Focus on risk and risk assessment. Gauging risk is a powerful personal trait and useful in our challenging world today; it builds the confidence to make good decisions. After all, confidence is the opposite of fear. The more confidence we have, the less fear we experience.
It’s good to take risks in life and have the confidence to face your fears.
