Self-confidence and courage hinge on the kind of thoughts you think.
Nurture negative thoughts over a long period of time and you are going to get negative results.
Your subconscious is very accomodating. It will sd up to you exactly what you send down to it.
Keep on sending it fear and self-inadequacy thoughts and that is what it will feed back to you.
Take carge of your mind and begin to fill it with healthy, positive and courageous thoughts.
