Therefore, keep happy.

Financially, Happiness pays. The happy salesman or saleswoman is more persuasive. The happy person gets and keeps more friends, who will like to help him, if only because his Happiness helps them. James Coates says:

Smile at your business, and it will smile back. Follow the light of that smile.

Therefore, keep happy.

Intellectually, Happiness helps us to see with surer clearness and foresight. Happiness helps us to solve our problems rightly. Happiness gives us more understanding and more intuition. Happiness makes us more receptive to the best ideas. Happiness puts us in better perspective. Happiness, once again, increases our mental energy, endurance, ease, and effectiveness.

These quotations from C. D. Larson are excellent. He says:—

Just be glad, and you always will be glad. You will have better reasons to be glad. You will have more and more things to make you glad.

When you are tempted to feel discouraged or disappointed, be glad instead. Just be glad, and your fate will change. Know that you can be glad, say that you will, and stand uncompromisingly upon your resolve. When things are not to your liking, be glad nevertheless, for the glad heart can cause all things to be as we wish them to be. When things do not give you pleasure, proceed instead to create pleasure in your own heart and soul.

It is the law that all good things will sooner or later come and be where the greatest happiness is to be found. Therefore, be happiness in yourself, regardless of times, seasons, or circumstances.

It is the man who blends rejoicing with his work who does the best work. It is profitable in every way to learn to be glad.
