I've just started going to a site that lists free kindle books where the author has temporarily reduced the price. I just got one yesterday... 'The Mind-Made Prison' has rave reviews. I'm just on chapter 1 and it seems to be a cross between The Secret and Tony Robbins, but still have a long way before finishing.
I just checked and it's still free, so thought people may be interested in it.
There's also another one today on goal setting -
How To Set Goals: Your Goal Setting Bible For Maximum Personal Achievement (it also has 5 star reviews!)
