People do not get tired out from working where work is intelligently handled. Work, if it is interesting, is a stimulant. It’s worry and a lack of interest in what one does that tire and discourage. Every one of us should have our pet interests-as many as we can handle efficiently and happily. Our interests should never be allowed to lag or get cold so that all enthusiasm is spent. Each day can be one of triumph if you keep up to your interests-feeding them as they feed you!
