Einstein's Theory of Happiness

I found a video yesterday talking about something called "Einstein's Theory of Happiness" - I wasn't sure whether to believe it or not, so I researched it further.  Apparently, the famous theoretical physicist and winner of the 1921 Nobel Prize in Physics, Albert Einstein was traveling from Europe to Japan to give a series of lectures on his Theory of Relativity.  It was on this trip that he learned that he had been awarded the 1921 Nobel Prize.  He had escaped to his hotel room at the Imperial Hotel in Tokyo in order to gather his thoughts and feelings when a messenger arrived with a delivery.  No one knows for sure the exact reasons, but Einstein was unable to give the messenger a cash tip (either the messenger refused or Einstein was short on cash).  Instead, Einstein wrote down a message on a piece of paper and handed it to the messenger.  According to legend, Einstein told the messenger something to the effect that "If you are lucky, the notes themselves will someday be worth more than my spare change."

The note was simple and succinct.  Einstein suggested that here was the secret for living a happy and fulfilling life:

A calm and modest life brings more happiness than the pursuit of success combined with constant restlessness.

There are very powerful words from a very brilliant individual.  And they are words that we all can and should live by in our own lives.  Incidentally, Einstein's suggestion that the note would be worth some money some day did, in fact, come true.  A resident of Hamburg, Germany claiming to be a descendent of the messenger apparently sold the note at auction for $1.56 million on October 19, 2017.  Not a bad return on investment.
