A survey by RHR International found that half of CEOs report experiencing feelings of loneliness in their roles. Of this group, 61% believe isolation hinders their performance. That’s a significant proportion of top executives who are suffering and not performing at their peak. Executive loneliness and isolation is bad for people and bad for business.

In my experience, fear and ego are two of the main causes of this kind of isolation. On the one hand, there’s fear of appearing inadequate and the concern that asking for help could make others doubt your judgment. After all, CEOs are supposed to have all the answers—the buck stops with you. Meanwhile, your ego is telling you that you really don’t need others to help make big decisions; who knows your business better than you do? Combined, these two factors can prevent even highly capable CEOs from turning to others for support when they need it most.
