Successful people are willing to do things unsuccessful people will not do.
Anyone can steer a ship, but it takes a leader to chart the course

Credibility is a leader's currency. With it, he or she is solvent; without it, he or she is bankrupt.
The higher you want to climb, the more you need leadership. The greater the impact you want to make, the greater your influence needs to be. Whatever you will accomplish is restricted by your ability to lead others.
