“Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.”

Albert Schweitzer, OM was a French-German theologian, organist, philosopher, and physician. He was born in the German province of Alsace-Lorraine and although that region had been reintegrated into the German Empire four years earlier, and remained a German province until 1918, he considered himself French and wrote mostly in French. His mother-tongue was Alsatian German.
