Books to train your brain to suchandsuch or thisandthat

If you want to buy a book to try to train your brain to do something, you have many somethings and many books to choose from. Here’s a sampling:

Train Your Brain to be a Genius , by John Woodward, 2009.
Train Your Brain to Get Thin: Prime Your Gray Cells for Weight Loss, Wellness, and Exercise , by Melinda Boyd and Michele Noonan.
Train Your Brain to Get Happy: The Simple Program That Primes Your Grey Cells for Joy, Optimism, and Serenity , by Aubele PhD, Teresa, Wenck, Stan and Susan Reynolds, 2011.
Train Your Brain to Get Rich: The Simple Program That Primes Your Gray Cells for Wealth, Prosperity, and Financial Security , by Teresa Aubele PhD, Doug Freeman JD LLM, Lee Hausner PhD, Susan Reynolds, 2011.

There is a near-infinity of other such books available for consideration by you or your brain. All of them may be equally effective.

Near-infinity extends in many (perhaps a near-infinity of) directions. In one direction, you can find the splendid Brain Train, invented by Ig Nobel Prize winner Bart Knols. In a very different direction, you can find BrainTrain.
