I have no regrets. I like the purity of mathematics. I can forget about everything else and focus on what I am working on. I like working with others, but I also like working alone. Both have their merits. Proving
something new or coming up with a new idea gives me the kind of
pleasure that can‘t be compared with any other experience.«
»In mathematics in general, it is important to take your time. It’s my
impression that mathematics requires much more time to reach a
novel result than other subjects. It is important not to hurry in
mathematics, because hurrying leads nowhere.
