It's sad how much we lose because of our fear of failure. So many opportunities vanish simply because we were too afraid to act.
How will we ever know the extent of our possibilities if we fear reaching our limits? I know, for myself, that most of my perceived limits are illusory. Yet it's uncomfortable to imagine stretching past them.
We must master our fears. If nothing else, transfer that to a fear of not trying, of the lost opportunity. That way our fears push us forward. Yet, I feel the ideal is centering ourselves upon love, passion. It's better to run towards success than away from terror. Fear exhausts; love's attraction energizes.
