Colin Powell
Leadership is solving problems. The day soldiers stop bringing you their problems is the day you have stopped leading them. They have either lost confidence that you can help or concluded you do not care. Either case is a failure of leadership.
If you are going to achieve excellence in big things, you develop the habit in little matters. Excellence is not an exception, it is a prevailing attitude.
Children need to get a high-quality education, avoid violence and the criminal-justice system, and gain jobs. But they deserve more. We want them to learn not only reading and math but fairness, caring, self-respect, family commitment, and civic duty.
There are no secrets to success. It is the result of preparation, hard work, and learning from failure.
