Try to get this book, it's not that expensive. It's great. Very simple in it's message but absolutely true. That's why it's so popular.

Basically (but still read it please) it says..........
If you keep on doing what you're doing, you'll keep on getting what you get.
(And that's fine if what you're doing is ok........but....what if your cheese moved? What if there were NO MORE CHEESE? What would you do? Would you starve? Are you that kind, who'd keep on going back to the disappeared cheese? Or are you a get up and go mouse? Would you search new cheese?)
All basic, but if read thoroughly, compounds the message (not subliminally) but enough to make a real impression.
Try it.
