The ultimate superpower, if you think about it, is the power to influence. Therefore, Dale Carnegie’s 1936 book on cultivating this superpower has a loyal following. The book’s tips include remembering to smile, giving sincere and honest appreciation, and arousing in the other an intense want. So, you don’t need to shoot webs out of wrists; your smile can charm Spidey into doing it. With it, you don’t need to fight crime in a bat costume; you can simply pick the right ‘thank you’ card to send Batman. Or, with it, you don’t need to be rich; you can trigger a compelling want in a rich friend, like a banker, to get him or her to spend for you.
