“Embedded in songs, emblazoned on skin, and embraced by sages, the anti-regret philosophy is so self-evidently true that it’s more often asserted than argued.” So writes Daniel Pink in his new book, “The Power of Regret: How Looking Backward Moves Us Forward.” There’s just one problem, he adds. The “no regrets” philosophy? It’s hogwash. Regrets may churn our stomachs, but they also improve our decisions and strengthen our values. They’re a photographic negative of the good life.

Some people think humans are natural pleasure seekers. But not psychologist Paul Bloom. In his new book, “The Sweet Spot,” Paul says we’re pain seekers, too. Just think about all the uncomfortable things we do for fun — eating spicy food, climbing treacherous mountains, watching scary movies, engaging in BDSM. Why do that stuff? According to Paul, it’s because pain can enhance pleasure, chosen suffering can make you more resilient, and adversity can suffuse your life with meaning. We can all benefit from a little discomfort, and in this intimate conversation with Next Big Idea Club curator Susan Cain, Paul explains how to fit more of it into our lives.
