My view is that at a younger age your optimism is more and you have more imagination etc. You have less bias.
The level of our success is limited only by our imagination and no act of kindness, however small, is ever wasted.
The reason we have poverty is that we have no imagination. There are a great many people accumulating what they think is vast wealth, but it's only money... they don't know how to enjoy it, because they have no imagination.
To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.
I cannot imagine a God who rewards and punishes the objects of his creation and is but a reflection of human frailty.
I have fallen in love with the imagination. And if you fall in love with the imagination, you understand that it is a free spirit. It will go anywhere, and it can do anything.
