Of all of the things that I value most about my abilities, intelligence is not top of that list. My ability to endure pain and suffering, my ability to work on something for a very, very long period of time, my ability to handle setbacks and see the opportunity just around the corner I consider to be my superpowers, and I hope they're yours.

I wanted to be an Olympic champion and I didn't care about the goings-on around me. In my heart and with all of my soul I was ready, willing and I was very able. I had a deadly sense of self-belief. I'd go to another level and say I had a deadly sense of self-conviction where you can say whatever you want, you can do whatever you want but you're not going to touch me.

Being a scientist is about resilience because science is exploring the unknown, just as an immigrant is exploring the unknown. In both, you are on an uncertain journey and you have to find your own North Star.

And finally, change requires more than just speaking out -- it requires listening, as well. In particular, it requires listening to those with whom you disagree, and being prepared to compromise. When I was a state senator, I helped pass Illinois's first racial profiling law, and one of the first laws in the nation requiring the videotaping of confessions in capital cases. And we were successful because, early on, I engaged law enforcement.

I would advise them to aim high. To set their sights at a pretty tough target and don’t be too worried if you’re not successful at first. Just keep persisting and keep improving your standards, getting better and better and ultimately, you’ve got a pretty fair chance at achieving your desired goal. ... But, I do think that virtually everybody that’s born has the ability to be very competent at doing something. I think that, in itself, is worthy of aiming towards, just to be competent at doing anything you particularly wish to do.

I can always remember, when I was at high school we had a school sort of army battalion and because, at that time, I was one of the larger boys, I was appointed sergeant of the number one platoon, and I was always absolutely petrified that when I was meant to turn the platoon left or turn it right, I was really actually hopeless at knowing quite what to do. But fortunately, my platoon, who were really all the misfits in the school, the larger misfits, they stood by me, and some of them were quite good at knowing when to turn left or turn right. So whatever command I gave, they would do the right thing. We were a pretty good platoon as a consequence although, at the time, I felt an absolute idiot.

I personally wouldn’t be, if I could possibly help it, involved in a serious pursuit in which there weren’t a few people who could laugh a bit about it. Because I can remember many occasions — maybe we’ve been stuck in a tent or we’re up on the side of a mountain, this heavy snow, avalanches all around us, and we can’t get up and we can’t get down, but we just sat in the tent and reminisced about occasions and days gone by and laughed about old jokes and all the rest of it. Then you really have a very good time, even though you’re sort of poised there between disaster both up and down. People who can make you laugh under those circumstances are very valuable indeed in an expedition.

Well, then of course, came the disaster in 1975, when my wife and my youngest daughter were flying into the Nepal hills where I was building a hospital and their plane crashed and they were killed. And this certainly, for me, was an absolute disaster, really because the two people that meant most to me in life had been killed in one fell swoop. It did take me quite a number of years to get over it. I found the only way to deal with it was to carry on very energetically, doing the things that we had all been doing together, which was largely building schools and things for the mountain people. Although, people used to say to me, “Time is the great healer,” certainly for the first two years I simply didn’t accept this. But, time was a great healer and after the years passed, the memories still remain. But, I think quite a lot of the pain tends to fade a little bit, and life did become a little bit easier.

I still regard adventure pretty much as a hobby to tell you the honest truth, and I think this approach to it keeps one refreshed almost. I think if you just regard adventure as a business, working becomes very boring as many other businesses can become. But even though adventure changed my life considerably, both in what I was doing and even economically, I’ve always regarded myself in a sense as a competent amateur.

I think motivation is the single most important factor in any sort of success. Physical fitness is important, technical skill is important, and maybe even the desire for money is important in some respects. But a sort of basic motivation, the desire to succeed, to stretch yourself to the utmost is the most important factor. Certainly in the field of exploration and activity, it’s the thing that makes the difference between someone who does really well and someone who doesn’t.
