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.

Life is short, and if we enjoy every moment of every day, then we will be happy no matter what happens or what changes along the way.

There are two great days in a person's life - the day we are born and the day we discover why.
