What is it that we are afraid of? Fear can be of eminent life danger, something real; or it could be imagined. If fear is real, we kind of know what to do, or ask for help; but if it’s not, it can be paralyzing. Real or not, fear is sabotaging our actions to move forward. Fear can and will keep you in mediocrity.
People with a healthy soul (thoughts, emotions, will) are able to overcome it by doing the very thing they are afraid of.
