Famous quotes containing the word constant:
“Young people of high school age can actually feel themselves changing. Progress is almost tangible. It’s exciting. It stimulates more progress. Nevertheless, growth is not constant and smooth. Erik Erikson quotes an aphorism to describe the formless forming of it. “I ain’t what I ought to be. I ain’t what I’m going to be, but I’m not what I was.””
—Stella Chess (20th century)
