Andrew abandoned all his other research.
He cut himself off from the rest of the world and for the next seven years
he concentrated solely on his childhood passion.
I never use a computer. I sometimes might scribble, I do doodles,
I start trying to find patterns really,
so I'm doing calculations which try to explain some little piece of mathematics
and I'm trying to fit it in with some previous broad conceptual understanding of some branch of mathematics.
Sometimes that'll involve going and looking up in a book to see how it's done there,
sometimes it's a question of modifying things a bit, sometimes doing a little extra calculation,
and sometimes you realise that nothing that's ever been done before is any use at all,
and you just have to find something completely new and it's a mystery where it comes from.
I must confess I did not think that the Shimura-Taniyama conjecture was accessible to proof at present.
I thought I probably wouldn't see a proof in my lifetime.
I was one of the vast majority of people who believe that the Shimura-Taniyama conjecture was just completely inaccessible,
and I didn't bother to prove it, even think about trying to prove it.
Andew Wiles is probably one of the few people on earth
who had the audacity to dream that you can actually go and prove this conjecture.
In this case certainly for the first several years I had no fear of competition.
I simply didn't think I or any one else had any real idea how to do it.
