Ever wonder why nothing seems to rattle great leaders? The best leaders are tough-minded; they keep moving toward their goals regardless of the ridicule or conflict they may face. Mental toughness is not necessarily something all leaders born with, but it is always something that you can learn. If you are going to excel and transcend in leadership, allow your tough mind and tender heart to work together. Remember, you cannot be too much of one thing and not enough of the other. You must find balance in everything—in your personal life, in business, and especially in effective leadership.
