Accept the challenges so that you can feel the exhilaration of victory.

Put your heart, mind, and soul into even your smallest acts. This is the secret of success.

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time. 

Work hard, stay positive, and get up early. It's the best part of the day.

The science of today is the technology of tomorrow.

When something is important enough, you do it even if the odds are not in your favor.

Do your work with your whole heart, and you will succeed - there's so little competition.

Start every day off with a smile and get it over with.

An early-morning walk is a blessing for the whole day.

Rather fail with honor than succeed by fraud.
