The power of doing anything with quickness is always prized much by the possessor, and often without any attention to the imperfection of the performance.

– Jane Austen

Pride and Prejudice, Chapter 10. Mr. Darcy says this to Mr. Bingley, who has just spoken about his own fast letter writing – "My ideas flow so rapidly that I have not time to express them." The thoughtful Darcy cautions that more speed means less attention to the quality of the performance.
