It may seem to your conceited to suppose that you can do anything important toward improving the lot of mankind. But this is a fallacy. You must believe that you can help bring about a better world. A good society is produced only by good individuals, just as truly as a majority in a presidential election is produced by the votes of single electors. Everybody can do something toward creating in his own environment kindly feelings rather than anger, reasonableness rather than hysteria, happiness rather than misery.
Life is all one piece. Men err when they think they can be inhuman exploiters in their business life, and loving husbands and fathers at home. For achievement without love is a cold and tight-lipped murderer of human happiness everywhere.
Life is made up of small pleasures. Happiness is made up of those tiny successes. The big ones come too infrequently. And if you don't collect all these tiny successes, the big ones don't really mean anything.
Love is an expression and assertion of self-esteem, a response to one's own values in the person of another. One gains a profoundly personal, selfish joy from the mere existence of the person one loves. It is one's own personal, selfish happiness that one seeks, earns, and derives from love.
Love is the condition in which the happiness of another person is essential to your own.... Jealousy is a disease, love is a healthy condition. The immature mind often mistakes one for the other, or assumes that the greater the love the greater the jealousy.
Man is supreme lord and master Of his own ruin and disaster, Controls his fate, but nothing less In ordering his own happiness: For all his care and providence Is too feeble a defence To render it secure and certain Against the injuries of Fortune; And oft, in spite of all his wit, Is lost by one unlucky hit, And ruined with a circumstance, And mere punctilio of a chance.
