by Richard Restak, M.D.

Think in terms of brain geography.
I was pretty worn out and demoralised after the first couple of pages and had lost the will to try and enhance my mental functioning. It seemed to require more cognitive effort than I was prepared to expend. Of the 28 short chapters or steps, only 19 and 21 appealed and fell within the limited effort I'm prepared to make:
Develop a tolerance for uncertainty and ambiguity
Increase mental acuity through wide and varied reading.
Apparently you're not meant to start in the middle so I'm giving up before I've started (wimp) but it does appear to be quite a realistic approach to improving your brain power. Do a bit more than me and let Richard Restak teach you how to be smarter through neuropsychiatry.
It comes highly recommended according to the blurbs on the back. Please read it and tell me whether it was worth the effort or not?
