I grew up in Cambridge in England, and my love of mathematics dates from those early childhood days.

However impenetrable it seems, if you don't try it, then you can never do it.

Always try the problem that matters most to you.

Some mathematics problems look simple, and you try them for a year or so, and then you try them for a hundred years, and it turns out that they're extremely hard to solve. There's no reason why these problems shouldn't be easy, and yet they turn out to be extremely intricate. Fermat's Last Theorem is the most beautiful example of this.

I was so obsessed by this problem that I was thinking about it all the time - when I woke up in the morning, when I went to sleep at night - and that went on for eight years.

Pure mathematicians just love to try unsolved problems - they love a challenge.

Just because we can't find a solution it doesn't mean that there isn't one.
