Gain Willpower: Practical Help to Overcome or Prevent Any Addiction or Impulse-Control Problem by Gradually Strengthening Elementary Character Traits

Summary from Author and Quote from Eminent Psychologist Dr. Roy F. Baumeister:The first topic in this book about sustainably increasing willpower regards my, the author's, novel conclusion. Specifically, addicts or those with impulse-control issues should have an easier time building the willpower needed to overcome their problems by their, at first, strengthening certain, seemingly insignificant character traits that are, in fact, fundamental to the establishment of personal self-control.

About this first topic and conclusion of mine, the following is a quote from the greatly distinguished professor, Dr. Roy F. Baumeister, who is one of our planet's most influential psychologists and a groundbreaking expert in the study of willpower. (He is, with John Tierney, also the author of the New York Times bestseller, Willpower: Rediscovering the Greatest Human Strength.)"[Rabbi Gruber's new understanding] is a good idea and much in keeping with the way I am thinking about [matters of willpower].
