We are in the age of the post-heroic leader. Once, to move up the corporate ladder and succeed at the top, you simply had to set goals, motivate the troops, delegate to underlings, and groom a successor—probably one who looked and behaved just like you.

But this white knight has become an anachronism. Whether a person is twenty-five or fifty, if they’re leading a team now, chances are that they’re managing a kaleidoscope of people from a variety of cultures and across a range of ages, all of whom are wired together 24/7. These changing demographics and structures have led to a seismic shift in terms of the tools needed to successfully manage and grow yourself and your team within a company: charisma and strategic-thinking abilities now matter less than qualities such as vulnerability and relatability.
