Put a lot of detail, color, sound, scent and life into these mental scenes.
Repeat your visualization often, with faith and attention, and your subconscious will accept these mental scenes as real experiences. The subconscious mind does not distinguish between real and imaginary experiences, and accepts both as real. It will start making changes and attracting opportunities, to make your reality match the images in your subconscious mind.
Actions, situations, and objects that you visualize frequently, eventually, manifest on the material plane in a natural way. This manifestation does not happen overnight. It needs time, and depends on how ambitious and sincere you are, and how much time and attention you put into this action.
You can use this process to change negative habits and build new, positive habits or skills. You can also use it for attracting money and possessions, for promotion at work, for building a business, improving health and relationships, changing circumstances, and for practically almost everything.
Pay attention to the thoughts you think. Do your best to reject negative thoughts, and to allow into your mind only thoughts that bring good, happy, and positive results.
