Well, 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.

I loved doing problems in school.
Andrew Wiles

Always try the problem that matters most to you.
Andrew Wiles

The definition of a good mathematical problem is the mathematics it generates rather than the problem itself.
Andrew Wiles

But the best problem I ever found, I found in my local public library.
Andrew Wiles

Perhaps the methods I needed to complete the proof would not be invented for a hundred years. So even if I was on the right track, I could be living in the wrong century.
Andrew Wiles

I'm sure that some of them will be very hard and I'll have a sense of achievement again, but nothing will mean the same to me - there's no other problem in mathematics that could hold me the way that this one did.
