Happiness is when what you think, what you say, and what you do are in harmony.

Mahatma Gandhi

Most folks are about as happy as they make up their minds to be.

Abraham Lincoln

If there were in the world today any large number of people who desired their own happiness more than they desired the unhappiness of others, we could have paradise in a few years.

Bertrand Russell

A lifetime of happiness! No man alive could bear it: it would be hell on earth.

George Bernard Shaw

Many persons have a wrong idea of what constitutes true happiness. It is not attained through self-gratification but through fidelity to a worthy purpose.

Helen Keller
