If you realize that all things change, there is nothing you will try to hold on to. If you are not afraid of dying, there is nothing you cannot achieve
Change begets change. Nothing propagates so fast. If a man habituated to a narrow circle of cares and pleasures, out of which he seldom travels, step beyond it, though for never so brief a space, his departure from the monotonous scene on which he has been an actor of importance would seem to be the signal for instant confusion. The mine which Time has slowly dug beneath familiar objects is sprung in an instant; and what was rock before, becomes but sand and dust.
As history has demonstrated many times over, change may arrive slowly or quickly but it is the one constant, in one form or another, on which we can all count.
It seldom happens that a man changes his life through his habitual reasoning. No matter how fully he may sense the new plans and aims revealed to him by reason, he continues to plod along in old paths until his life becomes frustrating and unbearable-he finally makes the change only when his usual life can no longer be tolerated.
I shall do less whenever I shall believe what I am doing hurts the cause and I shall do more whenever I shall believe doing more will help the cause. I shall try to correct errors when shown to be errors and I shall adopt new views so fast as they shall appear to be true views.
In two or three hundred years life on earth will be unimaginably beautiful, astounding. Man needs such a life and if it hasn't yetappeared, he should begin to anticipate it, wait for it, dream about it, prepare for it. To achieve this, he has to see and know more than did his grandfather and father.
