Greetings, SuperFriends! Today we are re-joined by Nelson Dellis. And this is a big deal, not just because Nelson is the 4-time USA Memory Champion, but because he was the 5th ever episode guest on this show! I think I've gotten a lot better at interviewing since then. Nelson, on the other hand, has gotten a lot better at many things, including writing. In fact, he came back to talk to us about the 2 books that he has published since, as well as about numerous climbs up some of the world's largest mountains. Nelson also runs a thriving charity called "Climb For Memory", and travels all around the world teaching these incredible memory techniques. We had a very far and wide-ranging conversation, where we talk about everything from dealing with failure, to the difference between being a subject matter expert and teaching. Of course, as you can expect, we go all the way to some memory hacks that you can implement in your own life. It's a great episode, and I always enjoy talking to Nelson. That is why he has become a SuperFriend in the years since he originally came on the show! So, I just know that you are going to enjoy this episode with Nelson Dellis! -Jonathan Levi
