Oh and Mr Buzan just brought up another point. The intro has and activity where you are suppose to imagine an object and then
Rotate it infront of you
look at it from the top
look at it from underneath
Change its color. Etc. "These feats can be performed by you without much difficulty"

Er.. I beg to differ, I am unable to picture anything when I close my eyes. Vauge vauge flashes of a thought/picture sometimes. I cannot even picture a circle or sqaure when I close my eyes.

In my readings ive come across this problem many times, is their any way to fix it? Im not an idiot ;p just special.
