"Try to make at least one person happy every day. If you cannot do a kind deed, speak a kind word. If you cannot speak a kind word, think a kind thought. Count up, if you can, the treasure of happiness that you would dispense in a week, in a year, in a lifetime!"
"The man who makes everything that leads to happiness depends upon himself, and not upon other men, has adopted the very best plan for living happily. This is the man of moderation, the man of manly character and of wisdom"
"I was married to Margaret Joan Howe in 1940. Although not a scientist herself she has contributed more to my work than anyone else by providing a peaceful and happy home"
