I think I have raised this before, the numbers of people that can actually do what you suggest are tiny. 

Of the billions only say 0.01 % will be even able to recognise this con job.

Also even if you are up for the challenge,  your playing with one foot tied to your leg  and one hand behind your back. 

Free will, its just a con to keep you in the game.

I know I may sound pessimistic, I'm not really.  Just give us the tools to get on with it and we will.
