“Every person should make it his business to gather new ideas from sources other than the environment in which he daily lives and works.
The mind becomes withered, stagnant, narrow and closed unless it searches for new ideas. The farmer should come to the city quite often, and walk among the strange faces and the tall buildings. He will go back to his farm, his mind refreshed, with more courage and greater enthusiasm.
The city man should take a trip to the country every so often and freshen his mind with sights new and different from those associated with his daily labors. Everyone needs a change of mental environment at regular periods, the same as a change and variety of food are essential. The mind becomes more alert, more elastic and more ready to work with speed and accuracy after it has been bathed in new ideas, outside of one’s own field of daily labor.”
