And the most fulfilled, centered, grounded, happy people I know are people who made the choice to be part of an effort to actually make the world a better place. ... I would say, to me, the path of least regrets is to at least make a short-term commitment to say, “Let me work to make a real difference in the world.” The worst that could happen is you decide to move into something else later, but you’ll always take with you what you’ve given and what you’ve gained through that experience.

I think fear and fear of the unknown and perceived failure is what holds people back. For me, I am more scared of complacency than having something not work out. I'd rather take a leap of faith and fall than stand on the edge forever.

Certainly, if you want to get into the field of biology these days, you should also study anthropology because so much work now is with communities. How do you help communities? How do you convince communities to protect their environment? — Especially if, let’s say, you have a tiger eating your cows. The natural gesture is to kill that tiger. Well, what are the alternatives? That’s the kind of thing one is now increasingly working with.

So any student who wants to get into psychology, right now the students are like lemmings. They say, “Well, it’s popular to study brain science, I’ll do that.” Or, “It’s popular to do neural networks; I see 30,000 people doing it, it must be good.” And my advice is if a lot of people are doing it, don’t waste your time.

Having found suitable men, our next problem was to keep them and nurture them until they were ready. To do that I had to give them work of significance to do, and not treat them as apprentices. As I allotted them important tasks, some of the old guard became apprehensive for their own positions. They saw no reason why these bright, young, energetic men who had not contributed to the struggle, should come in and displace them before they were ready to go.

Our young should prepare to seek their fortunes in this golden age. It is silly to moan that properties and cars are going out of their reach. They will never be out of reach of those who seize their opportunities. Of course those on profit sharing schemes and stock options will do better than those on salaries. But even those on salaries will have their salaries double in the next 10 years of high growth. The big winners will be those who find a vein of gold and dig it out. But you have to work to find it and dig it out. Those who bemuse and befuddle themselves into believing the great opportunities are already behind them will regret it when they see their more discerning and perceptive contemporaries prosper.
