I do not use special means to extend my time for work. I work as much as my strength allows, and strength obviously grows in proportion to what needs to be done. When nothing is urgent, I finish much earlier. Heaven certainly understands economics. What you cannot accomplish by nine in the evening is presumably no longer necessary. The fact that it does not go smoothly in practice according to rational laws is due to the fact that we are not pure spirits. There is no point in rebelling against it and getting upset about it.
(Edith Stein /1891–1942/, letter to K. Kopfová, October 12, 1927)
