We must understand that there are torments fear infuses into our lives on our way to accomplishing our dreams, which we must release ourselves from. 

Fear of the unknown is what so many people do mention as an obstacle. The fear borne out of the experiences of some people that took certain steps and failed. Mr A took such step, he failed. Mr B took the same step but failed. If I take similar step in the pursuit of my dream won't I fail?
