I lose anywhere up to 20 pounds on location with adventurers like Conrad Anker or Brady Robinson. So I need to replace that lost weight and muscle by training hard when I am back in the States between jobs. And as I get older, it is far more important for me to be doing this and taking my conditioning seriously.
I am always concerned with finding the right spot and the right shot, so sometimes I forget to appreciate the skill of my fellow adventurers, but I am aware of how my life has been changed by my ability with a camera.
You do wonder - when you are at 28,000 feet, the height that aeroplanes cruise at, when you are struggling to draw breath and every limb aches - why do I do this?
You learn over years of expeditions that having faith, and putting one foot in front of the other, you do end up pulling off climbs that seem completely impossible. There's a certain beauty to that. It has an allure.
I listen to everything while I train. From old school reggae, to classical stuff like Bach, to hip-hop, to rock and roll.
People say, 'Are you insane?' But the most successful climbers are the most calculating, with the most refined sense of risk. They're hyper-conscious of safety. They're the least insane people I know.
Becoming a parent has changed the risk calculus for me. But it might be age, too, and seeing a lot of friends die in the mountains. Will I take the same risks I took in my 20s? Probably not, but I will always push myself in the mountains.
I loved going to the Chiang Kai Shek Memorial in Taipei to watch all the old Chinese people doing tai chi and practicing kung fu. The monument was made of white marble, and it was beautiful. Sometimes my dad and I would practice with them.
So many diseases and illnesses have fundamental roots in the lack of clean water. Resolving the clean water crisis would mitigate a lot of problems.
Great images take you on a journey via a single photograph. The depth and layers pull your eye all over the frame, causing you to pick up interesting pieces along the way, ultimately coming to a climax.
As a professional climber, that's the question you always get: Why, why, why? It's an ineffable thing; you can't describe it.
As a professional climber and photographer, I am asked to shoot in a lot of situations with a lot of different people. Sometimes I'm with the hardest, most seasoned alpinists in the world. Sometimes I'm hanging out with celebrities doing a benefit climb.
On climbs, there is a general way we manage fear. We look at things objectively, separating out perceived risk from real risk. You can really bring down the level of fear by knowing the real risks and setting aside the others. You also know that panicking just makes things worse.
The climbs up the Hand of Fatima, which is 2,000 feet, and Naga Parbat, which is just over 15,000 feet, were spectacular. The Hand of Fatima and the Kaga Tondo, in Mali, is a personal favourite of mine.
I truly believe the intention of creating positive change is so important to the collective consciousness. When you have a group of people that have the intention and the capacity, talent, and intelligence to actualize those intentions, then you have something really powerful.
The mainstream audience has a certain picture of what climbing is all about: man conquering mountain. But you can't conquer a mountain, though it may conquer you.
I won't ski in the backcountry the day after a big storm anymore. The mountains are so humbling. As soon as you think you're on top or crushing it, that's when you need to be really careful.
I've tried to eat little shrubs before. We were on an unsupported 20-plus day traverse, following the migration of endangered antelope across the Chang Tang Plateau. We were like, 'Oh, this is what they ate; we should try it.'
Mountains are like the great equalizer. It doesn't matter who anyone is or what they do.
When you're climbing something as challenging as Meru, it's all about efficiency. Even a decision as small as what to eat for dinner would expend energy you need for making other, more dramatic decisions.
