He who has so little knowledge of human nature as to seek happiness by changing anything but his own disposition will waste his life in fruitless efforts.
Life affords no higher pleasure than that of surmounting difficulties, passing from one step of success to another, forming new wishes and seeing them gratified.
If your determination is fixed, I do not counsel you to despair. Few things are impossible to diligence and skill. Great works are performed not by strength, but perseverance.
