Now, this ideology gets policed by this one very dangerous question, which is, "What percentage of my donation goes to the cause versus overhead?" There are a lot of problems with this question. I'm going to just focus on two. First, it makes us think that overhead is a negative, that it is somehow not part of the cause. But it absolutely is, especially if it's being used for growth.

In my opinion, the key to dealing with the future lies in knowing where you are, even if you can't know precisely where you're going. Knowing where you are in a cycle and what that implies for the future is very different from predicting the timing, extent and shape of the next cyclical move.

I’d read some of the things that Don Glaser wrote, for example, and they’re imaginative physics, they’re not quite such good biology. There was a consensus that said you had to be able to reach out from physics and get to some of these things you’d like to, but then you have to know enough about the biology that the whole thing makes sense. And you really have to present things in such a way that a community develops. I didn’t realize that at the time, but certainly one of the important things of what I did had to do with enabling people who came from physics, or who came from biology, become a community, working on not just one little problem or piece, but somehow collectively working together toward trying to get an understanding.

And I'm not here to say that men are to blame for the crisis and what happened in my country. But I can surely tell you that in my country, much like on Wall Street and the city of London and elsewhere, men were at the helm of the game of the financial sector, and that kind of lack of diversity and sameness leads to disastrous problems.

In Rakuten's case, adjustment certainly took time. At first, meetings often felt awkward. The first board meeting after the Englishization decision took four hours to complete – double the normal duration. But whenever executives asked if they could say certain things in Japanese, I told them no. I knew that the challenge would pay off – and it has.
