Last time (see "What makes elite individuals elite?"), I posted about Diana Nyad and the studies performed by Martin Paulus and his team suggesting that perhaps there is a little bit of Diana Nyad in all of us. While we may never swim across the Straits of Florida like Nyad did on her fifth attempt in 2013, the work by Paulus and his team strongly suggest that we can train our minds to push beyond our own self-perceived limits.
I am reminded of a story that I heard about the American entrepreneur, author, ultramarathoner, and former rapper (under the name "Jesse Jaymes") Jesse Itzler. Incidentally, Itzler also happens to be married to another entrepreneur, Sara Blakely, the founder of Spanx. Itzler was running in a 100 mile ultramarathon as part of a relay team of five other runners, when he "met" former Navy SEAL David Goggins, who was running the entire 100 mile ultramarathon by himself! I've posted about Goggins in the past (see my post "GoRuck"). Goggins is a freak of physical fitness - he apparently joined the U.S. Air Force in the 1990's, gained a lot of weight after he left the Air Force, and then lost 106 pounds before joining the U.S. Navy and signing up for the U.S. Navy SEAL entry program, Basic Underwater Demolition/SEAL training ("BUD/S"). After completing training and qualifying as a Navy SEAL, Goggins completed U.S. Army Ranger School. He would serve in the military for 20 years, and he has since become an ultramarathoner, triathlete, ultra-distance cyclist, motivational speaker (of course), and author. And oh, did I mention that he once held the world pull-up record? He once did 4,030 pull-ups in a 17 hour period. He has since written two excellent memoirs, Can't Hurt Me: Master Your Mind and Defy the Odds and Never Finished: Unshackle Your Mind and Finish the War.
Back to Itzler. After meeting Goggins, Itzler did what only a billionaire could do - he hired Goggins to live with him for the next 30 days and teach his family the art of mental toughness. Itzler's experience is the subject of his book, Living with a SEAL. Itzler writes, "The first day that “SEAL” came to live with me he asked me to do — he said how many pull-ups can you do? I did about eight. And he said all right. Take 30 seconds and do it again. So 30 seconds later I got up on the bar and I did six, struggling. And he said all right, one more time. We waited 30 seconds and I barely got three or four and I was done. I mean couldn’t move my arms done. And he said all right. We’re not leaving here until you do 100 more. And I thought there’s no — well we’re going to be here for quite a long time because there’s no way that I could do 100. But I ended up doing it one at a time and he showed me, proved to me right there that there was so much more, we’re all capable of so much more than we think we are. And it was just a great lesson."
Goggins refers back to a statement that the American psychologist William James made in his book, The Energies of Man. James wrote, "Beyond the very extreme of fatigue and distress, we may find amounts of ease and power we never dreamed ourselves to own; sources of strength never taxed at all because we never push through the obstruction." Goggins calls it "the 40% rule". Itzler explains further that the "40% rule" simply means that when your brain is telling you that you can't go on anymore, you are really only 40% done. Deep down, your body can handle more stress and you can face even greater challenges.
I'd love to see what Goggins' right insula looks like on fMRI!
