It matters not what you inquire into, but whenyou once inquire into a thing, you must never give it up until you have thoroughlyunderstood it. It matters not what you try to think of, but when you once try to thinkof a thing, you must never give it up until you have got what you want. It matters notwhat you try to саrry out, but when you once try to carry out a thing, you must nevergive it up until you have done it thoroughly and well.
