To strive with difficulties, and to conquer them, is the highest human felicity; the next is, to strive, and deserve to conquer: but he whose life has passed without a contest, and who can boast neither success nor merit, can survey himself only as a useless filler of existence; ad if he is content with his own character, must owe his satisfaction to insensibility.
Samuel JohnsonIt may be observed in general that the future is purchased by the present. It is not possible to secure distant or permanent happiness but by the forbearance of some immediate gratification. This is so evidently true with regard to the whole of our existence that all precepts of theology have no other tendency than to enforce a life of faith; a life regulated not by our senses but by our belief; a life in which pleasures are to be refused for fear of invisible punishments, and calamities sometimes to be sought, and always endured, in hope of rewards that shall be obtained in another state.
Samuel Johnson
