Get some entire, active change for your brain, if it is only for fifteen minutes or half an hour. If you live in the city, even to go to walk and look into the shop windows is better than nothing. In that way you get fresh air, and if one knows how to look into shop windows without wanting anything or everything they see there, then it is very entertaining. It is a good game to look into a shop window for two or three minutes and then look away and see how well you can remember everything in it. It is important always to take shop windows that are out of one's own line of work. If you live in the country, a little walk out of doors is pleasanter than in the city, for the air is better; and there is much that is interesting, in the way of trees and sky, and stars, at night. As you walk, make a conscious effort to look out and about you. Forget the work of the day, and take good long breaths. When you do not feel like going out of doors, take a story book--or some other reading, if you prefer--and put your mind right on it for half an hour. The use of a really good novel cannot be overestimated. It not only serves as recreation, but it introduces us to phases of human nature that otherwise we would know nothing whatever about. A very great change from the day's work can be found in a good novel and a very happy change. If the air in the theaters were fresher and good seats did not cost so much a good play, well acted, would be better than a good novel. Sometimes it freshens us up to play a game after the day's work is over, and for those who love music there is of course the greatest rest in that. But there again comes in the question of cost. Why does not some kind soul start concerts for the people where, for a nominal admission, the best music can be heard? And why does not some other kind soul start a theater for the people where, for a very small price of admission, they can see the best plays and see them well acted? We have public libraries in all our cities and towns, and a librarian in one large city loves to tell the tale of a poor woman in the slums with her door barred with furniture for fear of the drunken raiders in the house, quietly reading a book from the public library. There are many similar stories to go with that. If we had really good theaters and really good concerts to be reached as simply and as easily as the books in our public libraries, the healthy influence throughout the cities would be proportionately increased. The trouble is that people cater as much to the rich with their ideas of a national theater as the theatrical syndicate itself. I could not pretend to suggest amusements that would appeal to any or every reader, but I can make my point clear that when one is tired it is healthy to have a change of activity before going to rest. "Oh," I hear, "I can't! I can't! I am too tired." I know the feeling.
