Cheerfulness is the greatest lubricant of all the wheels of life. It lessens pains, helps to fight against a disease, fades away misfortune, lightens burdens and eases one's life. There would be no need of hospitals in the world, if only people could be cheerful and light hearted.
Cheerfulness is indeed Therapeutic. It is a great physical, mental and spiritual tonic.
There is no personal charm, as great as a charm of a cheerful temperament.
It is the most certain sign of Wisdom.
