You will never do anything in this world without courage. 

It is the greatest quality of the mind next to honor.

Quality is not an act, it is a habit.

Love is a serious mental disease.

Music is a moral law. It gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything.

Every moment is a golden one for him who has the vision to recognize it as such.

It's fine to celebrate success, but it is more important to heed the lessons of failure.

Science is the great antidote to the poison of enthusiasm and superstition.

If you want to live a happy life,

Tie it to a goal, not to people or things.

Our age is merely the number of years the world has been enjoying us!

Happy birthday to You and may You have many many more!
