Life is like riding a bicycle. To keep your balance you must keep moving

Man becomes man only by his intelligence, but he is man only by his heart

Be regular and orderly in your life, so that you may be violent and original in your work.

Baseball has the great advantage over cricket of being sooner ended.

Golf is a day spent in a round of strenuous idleness

Mark Twain Quote
