The law of giving and receiving.

We are accustomed to think that a certain amount of time and energy is required to make the visible copy of the idea--the visible chair, or plow, or broom. But the more perfectly we think it out--that is, create it as a complete idea in mind--the more quickly and perfectly we can create it in visible form; and as we think it out better and better, we find that we require less and less time to make the visible thing-and less and less energy.
