G. H. Lewes
Let your pen fall, begin to trifle with blotting-paper, look at the ceiling, bite your nails, and otherwise dally with your purpose, and you waste your time, scatter your thoughts, and repress the nervous energy necessary for your task.
Science is the systematic classification of experience.
The magic of the pen lies in the concentration of your thoughts upon one object.
The real men of genius were resolute workers, not idle dreamers.
