To a large degree, since the beginning of time, charisma or the lack of it has impacted upon those in quest of acclaim. As media expands, this has become ever more vital. Thus, demeanor if unappealing, can defeat one's likelihood of success, causing the death of prospects whilst they are still embryonic.
Men of extraordinary success, in their honest moments, have always sung, "Not unto us, not unto us." According to the faith of their times, they have built altars to Fortune, or to Destiny, or to St. Julian. Their success lay in their parallelism to the course of thought, which found in them an unobstructed channel; and the wonders of which they were the visible conductors seemed to their eye their deed.
Be careful what you water your dreams with. Water them with worry and fear and you will produce weeds that choke the life from your dream. Water them with optimism and solutions and you will cultivate success. Always be on the lookout for ways to turn a problem into an opportunity for success. Always be on the lookout for ways to nurture your dream.
