It is important after all work, and especially for those who have some steady labor for the whole day.
Every one is more or less tired at the end of the day and the temptation is to drop into a chair or lie down on the sofa or to go right to bed and go to sleep.

Don't do it.
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.
