Try a hard problem. You may not solve it, but you will prove something else.

I listen only to Bach, Beethoven or Mozart. Life is too short to waste on other composers.

I constantly meet people who are doubtful, generally without due reason, about their potential capacity [as mathematicians]. The first test is whether you got anything out of geometry. To have disliked or failed to get on with other [mathematical] subjects need mean nothing; much drill and drudgery is unavoidable before they can get started, and bad teaching can make them unintelligible even to a born mathematician.

I recall once saying that when I had given the same lecture several times I couldn't help feeling that they really ought to know it by now.

A Miscellany is a collection without a natual ordering relation.

The infinitely competent can be uncreative.
