Quote by Albert Einstein
If A is success in life, then A = x y z. Work is x, play is y and z is keeping your mouth shut.

Summary
This quote suggests that success in life is a combination of three things represented by variables x, y, and z. The variables x and y respectively stand for work and play, indicating that both aspects are necessary for achieving success. However, the most important element represented by z is the ability to keep one's mouth shut, suggesting that maintaining discretion and not revealing everything one knows or thinks is crucial for achieving and sustaining success.
