I was lucky. When I was looking for an academic job in the early to mid-eighties, I looked to the success of the people who had graduated a few years before me to get some idea of my chances, naturally enough. To first order, it was pretty easy to calculate my chances. All the scientists a few years older than me had exactly the same success getting academic jobs: no success at all.
I admit to not finding this all that encouraging, but I nevertheless could not stop myself from working on science. And then, dumb luck came my way, as the job market for academics opened up at exactly the time I was looking for a position. At McGill, as a characteristic example, I and a few of my soon-to-be friends, were the first physicists hired in fifteen years. Versions of my story are shared by many scientists of my age (born in the mid to late 1950’s, a bit younger than baby-boomers). We could not stop ourselves from working on science despite the apparent long odds, and luck came our way. I don’t mean crazy world-changing, lottery-winning luck, I just mean lucky. If you want to be a scientist, you should really want it, because on top of everything else, you might just have to be a little lucky.
