Optimism

optimism. Doctrine, esp. as set forth by Leibniz, that the actual world is the best of all possible worlds; view that good must ultimately prevail over evil in the universe; sanguine disposition, inclination to take bright views. Oxford English Dictionary

What does optimism mean to you? A spring morning, with the daffodils in bloom, lambs springing about in the fields, and the sun shining. A monday morning, with all the week ahead yet to come. Perhaps it's sending in an application form for a fanlisting you've always wanted to build!

To the Japanese, the Chrysanthemum is the symbol of optimism and green is the most optimistic colour.
