The happiness of your life depends upon the quality of your thoughts.

Very little is needed to make a happy life; it is all within yourself in your way of thinking.

No man is happy who does not think himself so.

Very little is needed to make a happy life; it is all within yourself, in your way of thinking.

He who lives in harmony with himself lives in harmony with the universe.

To live happily is an inward power of the soul.

Happiness is no other than soundness and perfection of mind.

Think of what you have rather than of what you lack. Of the things you have, select the best and then reflect how eagerly you would have sought them if you did not have them.

Take care that you entertain no notions unsuitable to virtue and reasonable nature.
