Too many are like Douglas Jerrold's friend, who could converse in twenty-four languages, but had no ideas to express in any one of them.
"The only valuable kind of study," said Sydney Smith, "is to read so heartily that dinner-time comes two hours before you expected it; to sit with your Livy before you and hear the geese cackling that saved the Capitol, and to see with your own eyes the Carthaginian sutlers gathering up the rings of the Roman knights after the battle of Cannae, and heaping them into bushels, and to be so intimately present at the actions you are reading of, that when anybody knocks at the door it will take you two or three seconds to determine whether you are in your own study or on the plains of Lombardy, looking at Hannibal's weather-beaten face and admiring the splendor of his single eye." "The one serviceable, safe, certain, remunerative, attainable quality in every study and pursuit is the quality of attention," said Charles Dickens.

"My own invention, or imagination, such as it is, I can most truthfully assure you, would never have served me as it has, but for the habit of commonplace, humble, patient, daily, toiling, drudging attention."

"Be a whole man at everything," wrote Joseph Gurney to his son, "a whole man at study, in work, and in play." _Don't dally with your purpose_.
"I go at what I am about," said Charles Kingsley, "as if there was nothing else in the world for the time being.

That's the secret of all hard-working men; but most of them can't carry it into their amusements." Many a man fails to become a great man by splitting into several small ones, choosing to be a tolerable Jack-of-all-trades rather than to be an unrivaled specialist.
"Many persons seeing me so much engaged in active life," said Edward Bulwer Lytton, "and as much about the world as if I had never been a student, have said to me, 'When do you get time to write all your books?
How on earth do you contrive to do so much work ?' I shall surprise you by the answer I made.

The answer is this--'I contrive to do so much by never doing too much at a time.

A man to get through work well must not overwork himself; or, if he do too much to-day, the reaction of fatigue will come, and he will be obliged to do too little to-morrow.
