But this is very much the same as if thou shouldst be grieved because those who have lived before thee did not praise thee. 19. If a thing is difficult to be accomplished by thyself, do not think that it is impossible for man: but if anything is possible for man and conformable to his nature, think that this can be attained by thyself too. 20.
