This quote from Dr. Seuss to me means to not cry over something that occurred and cannot be changed, but be happy about it. The change in one’s life is a good thing, wither its for the better or worse. Without change in life it would be a mean less cycle reoccurring over and over. Smile is a powerful change in ones mood. Smile are used in happiness, sadness, and joy. I personally choose this quote because it reminded me of all the change that occurred in my life and how it helped me move on.
