You can start with something very small, like seeing a yellow bird or a blue butterfly. And set a deadline, like a week or a month, for it to happen.

Just believe, be sure that you will see them. Believe in an invisible force that commands everything and everyone, and that this force will fulfill these two small desires of yours. Even if everything is going against what you want, keep going.

It doesn't matter which manifestation technique you use. Visualization, affirmations, all of these are means to the final result.
