/ You see, 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 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 difficulty in laying his hands upon it. Now the skilful  |
| 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.              |
|                                                                                 |
