Dictionary.com defined fear as a distressing emotion aroused by impending danger, evil, pain, etc., whether the threat is real or imagined; the feeling or condition of being afraid.
In other words, fear is a conceived thought of something that is about to happen which also might not happen. It is to say that the emotions of fear are consciously manufactured by humans through thoughts. Unknowingly to us we are the sole creator of that same emotion we despised a lot and has retarded us from engaging in many worthwhile activities that ought to be beneficial to our being.
In summary, I want you to understand that whatever emotions of fear you have been going through that has kept you out from achieving worthwhile ventures, are mere imagery projections in your mind. It is by constant hoarding of these images of impending danger in our head that they tend to come to existence. So to say, whatever the mind can conceive in constant projection can take form in the physical realm. In a nutshell, if fear is a conceived emotion, it can also be displaced. All you need to do is to replace the emotions of fear with emotions of pleasantness and fill your mind with positive images and you shall have positive outcome in the physical realm.
