When you pluck a flower in the morning, by evening it withers if you don’t put its stem in water. Why? The flower does not take note that it is disconnected from the main plant. It continues to live as though it were still connected. It loses all the moisture it should have conserved, and it withers.

If we put 3 eggs in a basket each evening after work and take out two eggs for breakfast the next morning, in time, the basket would get full! As the Richest Man in Babylon teaches, CONTROL YOUR EXPENDITURES.
