Words of wisdom:

Whenever people agree with me I always feel I must be wrong. [Oscar Wilde]

The mathematician's patterns, like the painter's or the poet's must be beautiful; the ideas, like the colours or the words must fit together in a harmonious way. Beauty is the first test: there is no permanent place in this world for ugly mathematics. [Godfrey H. Hardy]

There's no sense in being precise when you don't even know what you're talking about. [John von Neumann]

Just because I'm paranoid doesn't mean they're NOT out to get me.

You'd be paranoid too, if people talked about you behind your back. [JMW]
