The only thing that keeps you from getting anything is the act of trying to get it.
Give up trying to get anything other than what you get and you will always get everything you want.
It may not always be the exact thing you had in mind before it appears but it will feel like exactly what you want when it appears or soon after. (how many times have you gotten something that was perfect that you had never thought of and how many times have you gotten exactly what you thought you wanted and it turned out to not be what you wanted after all?).
The achievement seminars of the future will be only one step: Give up trying to get anything other than what you get.
The other perhaps even more exciting result to doing this is that it allows you to eliminate worry about what might happen and be happy with everything that does happen.
