" A philosopher has remarked that if a man knew that he had thirty years of life before him, it would not be an unwise thing to spend twenty of those in mapping out a plan of living and putting himself under rule; for he would do more with the ten well-arranged years than with the whole thirty if he spent them at random. There is much truth in that saying. A man will do little by firing off his gun if he has not
learned to take aim. "

― Charles Haddon Spurgeon
