Context

“They ought to invest in themselves to increase creative value; after they have taken themselves to the peak of usefulness, then will be time enough to think of laying aside, as a fixed policy, a certain substantial share of income. You are not "saving" when you prevent yourself from becoming more productive. You are really taking away from your ultimate capital; you are reducing the value of one of nature's investments. The principle of use is the true guide. Use is positive, active, life-giving. Use is alive.” source
