What is the recipe of happiness?

The following formula has been suggested; it is credited to M Gorky the playwright:

H = H + W = C.

- _H stands for "Happieness"_

- _W is for "Work"_

- _C stands for "Contentment"_

What it mean is a combination of two Hs (one's own happiness - that comes from within - together with helping to bring happiness to others) combined with the joy and satisfaction obtained from meaningful Work produce Contentment - one of the keys to lasting happiness.
