This quote reminds me of the John Lennon quote elsewhere on this website. While his quote (disputed whether or not he really said it) talked about the importance of happiness this one gives an enlightened view on how you look at things to bring about that happiness.
I feel that this quote could be deeper. It almost makes you feel that you will be happier if you settle for what you have and I would prefer to look at it in the light of expressing gratitude and seeing the joy for what you have instead of ‘making the best of it’.
