If you think about your failures from the past, you stop believing in yourself, lose your enthusiasm and get frustrated. Visualizing images of a positive future helps you work from the present towards the future, without allowing the past failures to have any negative influence on you. You visualize yourself as a person, who has already overcome his fears and negative habits, and the fears are removed and the negative habits are transformed.You see yourself already transformed e.g. you say “I am a soul full of all powers” and not “I am going to or am trying to fill myself with all powers “. The power of that vision and the positive affirmations, combined together, is such that it helps you to bring about a major change in yourself, not just a small change, because you make it easy for your sub-conscious mind that is sleeping to wake up and realize its potential. You stop always expecting the worst and hope for, visualize and believe in the best.
