It's graduation season, and this year, U.S. colleges and universities will propel 1.8 million young people into the working world. While not all aspire to land in the C-suite, some have their sights set on the top job, either by founding a company or climbing the corporate ladder. With the likes of Mark Zuckerberg, Evan Spiegel, and Elon Musk, recent years have seen a surge of “Under 30 CEOs.” And though the average age of CEOs is slightly declining, today’s graduates may have expectations for advancement that don’t match reality. So what does it really take to get to the top? To guide the next generation, I interviewed three successful and prescient CEOs. I asked them to project which abilities will be required of their future counterparts, and what advice they’d give to young people who aspire to become a CEO.
