I would have made the quotation below, attributed to Albert Einstein, a “quote of the day”, but I have yet to find the original source from which it derives. If you know where it comes from, do let me know!
“If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music. … I get most joy in life out of music.”
