One of the things he (Ben-Gurion) said — and I liked very much — he said, “All experts are for things that happened. You don’t have experts for things that may happen” — which means, as he said, “If you really want to learn something, it’s not enough to be up-to-date; you have to be up-to-tomorrow.” That would be my first lesson, to look for the tomorrow. And eventually, I lost partly my interest in history, and I devoted most of my intellectual energies to the future. To this very day, I believe to imagine is more important than to remember. I don’t believe in memories anyway, because memories in a way is to remember what to forget. You hardly remember the things that were not easy or were not right, and yet people think it is more important to remember than to think. That was my first lesson. My second lesson is, “Your best friends are not only human beings, but books.” To read books is like going to swim in a sea of wisdom, endlessly fascinating. And there are so many wise people all over the world, throughout history, and you can have it free, for nothing. And reading must become a daily habit. It’s not that you can read once a week. I read day in and day out, and you make acquaintances with books. After a few pages, you know with whom you are dealing. Serious, unserious, far-sighted, repetitive. That was my second lesson. My third lesson was, “Never forget there is nothing wiser than a moral choice.” And the fourth point: “Don’t be afraid to be alone.” Future is always in a minority. So, if you want to be popular, go and praise the past. If you want to serve the future, don’t be afraid to belong to a minority.
