Shine a little light...

Aim at the moon and you will harpoon a fish,
Aim at a fish and you will harpoon a fish,
So you may as well aim at the moon. - Chinese Proverb

This might not be a yew tree it, but it made me think of the poem 'The Moon and the Yew Tree' by Sylvia Plath.

In the beginning there was nothing. God said, 'Let there be light!' And there was light. There was still nothing, but you could see it a whole lot better. - Ellen DeGeneres
