You do not have to erase negative thoughts you have had. All you have to do is feel good and think good thoughts right now, and you will shift yourself to a completely different frequency where no negativity exists. No matter what you have thought in the past, whether ten years ago or one minute ago, NOW is where all your power is. Right NOW you can use your power and shift yourself. When you know this, you can move through your life without fear or regrets, because you can always think good thoughts NOW.
-from The Secret Daily Teachings, written by Rhonda Byrne
If it sounds like work to drag what you want out of the invisible and into the visible, try this shortcut: see what you want as absolute fact. This will manifest what you want with the speed of light. The second you ask, it is fact in the Universal spiritual field, and that field is all that exists. When you conceive something in your mind, know it is a fact, and there can be no question about its manifestation.
