Change and Growth

I saw this bumper sticker on a car as I was rode the Mundo yesterday...I was feeling stressed (self-imposed, no doubt) and when I saw this it made me smile. The message did it's job, I suppose.

I'm curious if there is a person who originally said this or if it is just a catchy phrase to sell $2 bumper stickers. Googling it I only found one reference to its originator so I don't know if it is accurate. A blog writer claims that it was originally said by Walt Disney, which would actually make sense because he was supposedly a proponent of positive thought and reportedly  a member of the Rosicrucian Order.

Still not sure who said it, but it made me smile and relieved a little stress...and that--to me--is really all that mattered at the time.
