Set goals, challenge yourself, and achieve them. Live a healthy life...and make every moment count. Rise above the obstacles, and focus on the positive.

How many more years I shall be able to work on the problem I do not know; I hope, as long as I live. There can be no thought of finishing, for 'aiming at the stars' both literally and figuratively, is a problem to occupy generations, so that no matter how much progress one makes, there is always the thrill of just beginning.

It is difficult to say what is impossible, for the dream of yesterday is the hope of today and the reality of tomorrow.

The dreams of yesterday are the hopes of today and the reality of tomorrow.

The reason many people fail is not for lack of vision but for lack of resolve and resolve is born out of counting the cost.

Set goals, challenge yourself, and achieve them. Live a healthy life...and make every moment count. Rise above the obstacles, and focus on the positive.

No matter how much progress one makes, there is always the thrill of just beginning.
