Famous quotes containing the words energy and/or threshold:
“All my energy and attention were devoted to trying to help her solve her problems. Unfortunately I didn’t have much success.”
—Arthur Miller (b. 1915)
“I am admonished in many ways that time is pushing me inexorably along. I am approaching the threshold of age; in 1977 I shall be 142. This is no time to be flitting about the earth. I must cease from the activities proper to youth and begin to take on the dignities and gravities and inertia proper to that season of honorable senility which is on its way.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
