I've gotten over my shyness from many years of doing public events.

I live out of my van, which gives me a first-hand appreciation for power and lighting. A few years ago, I rebuilt the interior of my van to include solar panels and a battery that powers LEDs for lighting and allows me to charge my phone and laptop.

You might get run over; you might get hit by lightning. I mean, who knows? Each day, there is a chance you might die. And there's nothing wrong with that. Every living being on Earth is facing that same existential rift.

In the years after the expedition to Chad, I started the Honnold Foundation, a small nonprofit that was my attempt to do something positive in the world. I sought out projects that both helped the environment and improved peoples' standards of living. The more I researched, the more I gravitated toward solar.

When I was a teenager, I did a lot of pull-ups and push-ups. Every night before bed, I'd do 150 - in sets of 30 or so. Looking back on it now, I'm not totally sure that's the best way to improve as a climber. But it did make me a lot better at doing pull-ups and push-ups.

I've done routes where I've climbed 200 feet off the ground and just been, like, 'What am I doing?' I then just climbed back down and went home. Discretion is the better part of valor. Some days are just not your day. That's the big thing with free soloing: when to call it.
