When your soul is bored you must work.
I am not apt to follow blindly the lead of other men
There is no friend as loyal as a book
Painting is poetry that is seen rather than felt, and poetry is painting that is felt rather than seen
Mathematics is the language in which God has written the universe
Everything that has a beginning has an ending. Make your peace with that and all will be well
