Do think twice

"Do Think Twice is for people who still get excited by challenging new ideas, who enjoy stretching their minds and opening their hearts with head-scratching, brain-bending, assumption-crunghing possibilities, spiced with zesty dashes of humor. Between these covers are discoveries, insights, and creative speculations from 40 years of study and personal experience. As a bonus, Do think Twice offers time-tested techniques for applying the book's principles in daily life."--P. [4] of cover.
