The legendary personal achievement philosopher Jim Rohn said, “Income seldom exceeds your personal development.” As businesspeople, we frequently become laser-focused on the bottom line and all it entails—marketing, sales, spreadsheets—and we ignore the most essential ingredient in our success: ourselves.

If our sense of self-worth is integral to achieving—and sustaining—success, how much longer can we afford to overlook it?
