Colin Powell

I think whether you're having setbacks or not, the role of a leader is to always display a winning attitude.

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.

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

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

Perpetual optimism is a force multiplier.
