"For in all adversity of fortune the worst sort of misery is to have been happy"

"Behind every great fortune lies a great crime"

"Fortune brings in some boats that are not steered"

"I feel happy to terrify kids"

"There is a tide in the affairs of men, Which taken at the flood, leads on to fortune. Omitted, all the voyage of their life is bound in shallows and in miseries. On such a full sea are we now afloat. And we must take the current when it serves, or lose our ventures"

"There is only one person who could ever make you happy, and that person is you"

"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"

"Happiness is the only good. The time to be happy is now. The place to be happy is here. The way to be happy is to make others so"

"Happy is the person who knows what to remember of the past, what to enjoy in the present, and what to plan for in the future"

"Fortune is like the market, where, many times, if you can stay a little, the price will fall"

"No man is happy who does not think himself so"
