I would guess you found the last posts (see Future Pacing) to be very simplisitic and unbelievable. I can tell you from personal experience that it is extremely powerful.
The difficulty ia the well formed outcome. If you really want the outcome unconditionally, the exercise will really make a difference. Try it first with somthing simple that you really want to change.
For example brushing your teeth before you go to bed. Use the procedure and as long the it past the simple question, future pacing will create the behavior.
Try it with something simple.
