For 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. He that labours in any great or laudable undertaking, has his fatigues first supported by hope, and afterwards rewarded by joy... To strive with difficulties, and to conquer them, is the highest human felicity.
Samuel JohnsonHuman happiness has always its abatements; the brightest sunshine of success is not without a cloud.
Samuel Johnson
