I had this rare privilege of being able to pursue in my adult life, what had been my childhood dream.

The only way I could relax was when I was with my children.

Then when I reached college, I realized that many people had thought about the problem during the 18th and 19th centuries and so I studied those methods.

I loved doing problems in school.

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.

I carried this problem around in my head basically the whole time. I would wake up with it first thing in the morning, I would be thinking about it all day, and I would be thinking about it when I went to sleep. Without distraction I would have the same thing going round and round in my mind.
