As a scientist, my glass is always 100% full: with water and air

I'm an optimist, but an optimist who carries a raincoat

I am an optimist... I choose to be. There is a lot of darkness in our world, there is a lot of pain and you can choose to see that or you can choose to see the joy. If you try to respond positively to the world, you will spend your time better.

For myself I am an optimist - it does not seem to be much use to be anything else.

For some reason, I just loved it. There was a sense of optimism and joy in the 1920s.

You may exist in
this world--but I exist too
and I will not yield
