Brant

“He had been educated in no habits of application and concentration. The system which had addressed him in exactly the same manner as it had addressed hundreds of other boys, all varying in character and capacity, had enabled him to dash through his tasks, always with fair credit and often with distinction, but in a fitful, dazzling way that had confirmed his reliance on those very qualities in himself which it had been most desirable to direct and train. They were good qualities, without which no high place can be meritoriously won, but like fire and water, though excellent servants, they were very bad masters. If they had been under Richard’s direction, they would have been his friends; but Richard being under their direction, they became his enemies.”
― Charles Dickens, Bleak House
