A dream doesn't become reality through magic it takes sweat, determination and hard work.

My own experience is use the tools that are out there. Use the digital world. But never lose sight of the need to reach out and talk to other people who don't share your view. Listen to them and see if you can find a way to compromise.

Success is the result of perfection, hard work, learning from failure, loyalty, and persistence.

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.

There are no secrets to success. It is the result of preparation, hard work, and learning from failure.

We need to understand that we as citizens and as a government in any community throughout this country have no more important obligation than to educate those who are going to replace us.

When you decide to get involved in a military operation in a place like Syria, you've got to be prepared, as we learned from Iraq and Afghanistan, to become the government, and I'm not sure any country, either the United States or I don't hear of anyone else, who's willing to take on that responsibility.

We got rid of a terrible dictator. We gave the Iraqi people an opportunity for a new life under a representative form of government.

We all hoped in 2001 that we could put in place an Afghan government under President Karzai that would be able to control the country, make sure al-Qaeda didn't come back, and make sure the Taliban wasn't resurging. It didn't work out.

Great leaders are almost always great simplifiers, who can cut through argument, debate and doubt, to offer a solution everybody can understand.
