When crafting ones wishes, one should have at least some minor element of realism.

Also, your wish should be something your subconscious can help you with. For example, instead of wishfully thinking about money appearing in your bank account, you could wishfully think about finding it on the sidewalk. Or, alternatively you could wishfully think about yourself as a money magnet.

If you previously did not bear such points in mind, you might want to consider revisiting the technique, to see if you can make something of it. Unless you figure you are already too optimistic, that is.
