The children's book The Little Engine That Could was published in the 1930s. The story has been written and adapted by many, but the best known version was written by Walter Piper (a pen name used by Arnold Munk, owner of Platt & Munk publishing).  The story is about a little blue engine that carries a load of toys and other consumables across a mountain even though the little engine is too small for the job, he never stops thinking he can do it.  The main tag line from the story is, "I think I can, I think I can."
