“I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has a difficulty in laying his hands upon it. Now the skillful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
― Arthur Conan Doyle, A Study in Scarlet

“The less you eat, drink, buy books, go to the theatre or to balls, or to the pub, and the less you think, love, theorize, sing, paint, fence, etc., the more you will be able to save and the greater will become your treasure which neither moth nor rust will corrupt—your capital. The less you are, the less you express your life, the more you have, the greater is your alienated life and the greater is the saving of your alienated being.”
― Karl Marx, Economic & Philosophic Manuscripts of 1844
