Dr. Joyce Brothers is a popular American psychologist. She continues to appear in television, radio, and film.
“Studies indicate that the one quality all successful people have is persistence. They’re willing to spend more time accomplishing a task and to persevere in the face of many difficult odds. There’s a very positive relationship between people’s ability to accomplish any task and the time they’re willing to spend on it.”
– Dr. Joyce Brothers (1928- )
