If A equals success, then the formula is A = X + Y + Z. Where X is work. Y is play. Z is keep your mouth shut

Albert Einstein

Albert Einstein (14 March 1879 – 18 April 1955) was a German theoretical physicist who developed the theory ofgeneral relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics. Einstein is generally considered the most influential physicist of the 20th century. While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed « the world’s most famous equation »), he received the 1921 Nobel Prize in Physics « for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect ». The latter was pivotal in establishing quantum theory within physics.
