So Cambridge rejected me. Quite rightly, although at the time I thought it was a little churlish. So, I had to do it without any university training. ... and I began to realize that there were probably a lot more of these things, and that if you find these things, you get a position in the ladder which you can’t get to unless you have either got an education or something else. So by finding important things, you immediately get into the game, which you’d been excluded from otherwise.
