" The main obstacle to success he soon discovered to be Letty's exceeding distrust of herself. I would not be mistaken to mean that she had too little confidence in herself; of that no one can have too little. Self-distrust will only retard, while self-confidence will betray. The man ignorant in these things will answer me, " But you must have one or the other." " You must have neither," I reply. " You must follow the truth, and, in that pursuit, the less one thinks about himself, the pursuer, the better. Let him so hunger and thirst after the truth that the dim vision of it occupies all his being, and leaves no time to think of his hunger and his thirst. Self-forgetfulness in the reaching out after that which is essential to us is the healthiest of mental conditions. One has to look to his way, to his deeds, to his conduct--not to himself. In such losing of the false, or merely reflected, we find the true self. There is no harm in being stupid, so long as a man does not think himself clever; no good in being clever, if a man thinks himself so, for that is a short way to the worst stupidity. If you think yourself clever, set yourself to do something; then you will have a chance of humiliation. With good faculties, and fine instincts, Letty was always thinking she must be wrong, just because it was she was in it--a lovely fault, no doubt, but a fault greatly impeditive to progress, and tormenting to a teacher.
