Mathematical Formula for success...

It is said that according to Albert Einstein, one of the greatest geniuses the world has ever seen, success can be defined by the following formula: S=x+y+z S=success x=work y=play z='keeping one's mouth shut' This is very interesting for every aspirant for sucess and prosperity in life..... Many things can said and written on the subject...but it ,in my view the formula is not at all debatable.... Once upon a time I said to SOME OF my friends at TECHNO INDIA that NEWTON'S LAWS OF MOTION ARE EQUALLY FOR HUMAN LIFE ,PHILOSOPHICALLY....for example, every action has equal and opposite reaction.......though the timing ogf the reaction to act may vary as per the real-life situations..
