A few years ago, I was walking down the street when I came across this discarded mattress with a message that has since become my mantra for living. It said: "Don't Let Idiots Ruin Your Day." THANK YOU, wise mattress. Your words have helped me bounce back from many a messy, morning commute (amongst other things). Street mattresses are the best-form of self-help because sometimes, all the answers you seek can be found in bed. Click onward for some mattress wisdom that will help get you through any dark day.
