I stand up for what I believe in, and I believe in a lot of things.
I'm not a person who likes to be regular.
I don't have any particular recipe [for developing new proofs] ... It is the reason why doing research is challenging as well as attractive. It's like being lost in a jungle and trying to use all the knowledge that you can gather to come up with some new tricks, and with some luck you might find a way out.
A true leader listens more than they speak, learns more than they teach.
The writer of originality, unless dead, is always shocking, scandalous; novelty disturbs and repels.
None but the brave deserves the fair.
