Try this excersize
Get some blue-tack or a post-it-note or something sticky, then find yourself a high wall (in a room may not be high enough.) The external wall of your house would be good.
READ ONLY THE NEXT TWO PARAGRAPHS, THEN COME BACK TO READ THE REST!
Now, with your very best effort, leap as high as you can and stick whatever you have to the wall.
Stand back and admire how well youv’e done. Now get another sticky and try to beat it.
Well? Beat it didn’t you. 99 times out of a 100, we are able ‘to beat our best’. The human mind is an amazing place and infinately complex.
Fortunately, we know how to access the corners of the mind that you think you can’t access and free them to allow you to realise goals and ambitions you thought were out of your reach.
