If you’re hoping to climb to the top of the corporate ladder, a professor at the Wharton School of Business has a recommendation: Don’t play golf! You heard that right. Writing on the website of Psychology Today, Adam Grant, a Ph.D. in organizational psychology and a “leading expert on success, work motivation, and helping and giving behaviors,” lists six “perks of celebrity life” that he says are bad for new CEOs. Among them: using the corporate jet for personal use, buying a mansion, winning awards, writing books, and serving on other companies' boards. But his number-one admonition is “Don’t play golf.” After admitting that good golfers make more money as CEOs, he goes on “the time they spend on the golf course hurts their companies,” quoting a study that found that as chief executives, “golfers perform worse than non-golfers and [corporate] performance decreases with golfing ability.” He also recommends turning down invitations to tee it up with “important people.” And here we thought one of the main reasons for becoming a CEO was to play golf.
