Do a deep reflection on what exactly went wrong and write it down. Please don't do that lazy analysis where you just blame government, the economy, the markets, fundraising etc. It might have been a contributing factor and you should reflect that but please do that uncomfortably deep and introspective work of figuring out where *YOU* the founder went wrong.

The advice I would give any young person is, first of all, to rid themselves of prejudice against other people and to be concerned about what they can do to help others. And of course, to get a good education, and take advantage of the opportunities that they have. In fact, there are more opportunities today than when I was young.

The most important piece of advice that I could give them is to take advantage of the tremendous reservoir of knowledge that’s out there today. Spend some time learning how the world has evolved. There are a lot of good lessons in history, and other peoples’ experiences in the past, that could be exactly the solution to the problem you’re looking for.

Courage is more exhilarating than fear and in the long run it is easier. We do not have to become heroes overnight. Just a step at time, meeting each thing that comes up, seeing it is not as dreadful as it appeared, discovering we have the strength to stare it down.

What in a way pleases me and makes me very proud, and I probably shouldn't be, is that I am an honorary fellow of the five oldest academies of the world, all five of them and I don't know whether there's anybody else who can say that.

I always think about things, and if something puzzles me… Well, that of course was one of Darwin’s secrets. Whenever something puzzled him, he tried find a theory. He made a conjecture, as (Karl) Popper would call it, and see if it worked out and that’s true even today.

Very often I had to fight for the recognition of my ideas, particularly since, in those earlier days, I wasn’t in any prominent position where people would listen to me.

No sir. I'm rather dismayed how many days I have to work on my willpower very strongly in order to get out of bed before 8 o'clock.…I write letters, I write manuscripts, in addition to the book that is in press I have two manuscripts that are going to be published some time this or next year, and I have a whole list of manuscripts that I would like to write.
