Albert Einstein's thoughts on the secret to happiness have been revealed thanks to handwritten notes from the genius which have surfaced after 95 years.
The German-born physicist dedicated his life to science, but suggested in the notes that fulfilling a long-term ambition doesn't necessarily guarantee happiness.
His thoughts on the pursuit of happiness were revealed in the notes written for a courier he met in 1922, according to The Telegraph UK.
The theoretical physicist, who is celebrated for his groundbreaking theory of relativity, was on a lecture tour in Japan when the encounter took place.
