He that floats lazily down the stream, in pursuit of something borne along by the same current, will find himself indeed moved forward; but unless he lays his hand to the oar, and increases his speed by his own labour, must be always at the same distance from that which he is following.
Samuel JohnsonTo have the management of the mind is a great art, and it may be attained in a considerable degree by experience and habitual exercise... Let him take a course of chemistry, or a course of rope-dance, or a course of any thing to which he is inclined at the time. Let him contrive to have as many retreats for his mind as he can, as many things to which it can fly from itself.
Samuel Johnson
