Be a courageous leader who illuminated flaws instead of hiding them. The ability to be vulnerable is such an important aspect of life that I switched the two words sitting on my nightstand from "Thank You" to "Radical Humility," as a reminder to be humble and allow myself to be vulnerable.

And it's not simply being vulnerable as a person at home with your family; it is essential to also be vulnerable as a leader in business.

Vulnerability is simply the courage to be yourself, "warts and all," a core component of effective leadership. Leaders who try to portray themselves as invulnerable or perfect will soon find that their message does not resonate with their team.

Not only that, but a façade of invulnerability is a defense which attracts attacks from others. Vulnerability means living in authenticity.
