Fear is never a reason for quitting; it is only an excuse.
There are two primary forces in this world, fear and faith. Fear can move you to destructiveness or sickness or failure. Only in rare instances will it motivate you to accomplishment. But faith is a greater force. Faith can drive itself into your consciousness and set you free from fear forever.
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.
