I have used a similar "saying" in the past... I once complained about my shoes, and then I met a man who had no feet.
I've never known where it originated but it helped me to be thankful for what I had.
I think we all would have been better off had we met Mr. Zurcher but I am so glad that you had the opportunity and shared his life lesson with us!
