I've heard it said that we're born with only a few fears - like the fear of falling and the fear of loud noises. All other fears we learn along the way. Like the fear of failure, the fear of rejection - even a fear of success. I believe our greatest enemy in life is fear, because fear keeps us from doing many of those things we would like to do that would make our life more complete and more enjoyable.
Doubt is the first cousin of fear and precedes it. We weren't born with doubt. Our habit of doubt has grown throughout our life. If we dwell on a doubt and give in to it, it then grows into fear.
You see doubt makes us ineffective, like a sea that is tossed and driven by the wind; every decision you make will be uncertain, as you turn first this way, and then that."If most of our fears and all of our doubts are learned along the way, then we can "unlearn" them by becoming masters of our thoughts.
"You see true courage is not the absence of fear, it's the mastery of fear." The people who live the life of their dreams have just as many fears as those who live miserable, unfulfilled lives - they just learned to master their fears instead of allowing their fears to master them.
