"The only prudence in life is concentration...." - Quote by Ralph Waldo Emerson

“An artist spends himself like the crayon in his hand, till he is all gone.”

“The power of a man increases steadily by continuing in one direction.”

“Let us not forget the genial miraculous force we have known to proceed from a book.”

“Whatever you are doing, put your whole mind on it. If you are shooting, your mind should be only on the target. Then you will never miss. If you are learning your lessons, think only of the lesson. In India boys and girls are taught to do this.”

“The mind generally takes up various objects, runs into all sorts of things. That is the lower state. There is a higher state of the mind, when it takes up one object and excludes all others.”

“I can't concentrate when I'm thinking.”

“Don't go getting mixed up in the business of your betters, or you'll land in trouble too big for you.”

“Thin-lipped wisdom spoke at her from the worn chair, hinted at prudence, quoted from that book of cowardice whose author apes the name of common sense.”

“This is no time to lend money, especially upon bare friendship without security.”
