Every human being has a work to carry on within, duties to perform abroad, influence to exert, which are peculiarly his, and which no conscience but his own can teach.

Do anything rather than give yourself to reverie.

Every human being is intended to have a character of his own; to be what no others are, and to do what no other can do.

Difficulties are meant to rouse, not discourage. The human spirit is to grow strong by conflict.
