From The Guardian:
A Japanese courier arrived at the Imperial Hotel in Tokyo to deliver Einstein a message. The courier either refused to accept a tip, in line with local practice, or Einstein had no small change available.
Either way, Einstein didn’t want the messenger to leave empty-handed, so he wrote him two notes by hand in German, according to the seller, a relative of the messenger.
The handwritten note from 1922 recently sold at auction for $1.5m. The note described Einstein’s theory for living a happy life. It reads:
“a quiet and modest life brings more joy than a pursuit of success bound with constant unrest”.
Well said. This is Einstein and his second wife Elsa in 1921, a year before he wrote the note and won the Nobel Prize for Physics:
