What you learn living one month with a Navy SEAL

Retired Navy SEAL David Goggins has a saying: When your brain says that you’re done, you’re only 40 percent done.

It’s something Jesse Itzler, an Atlanta Hawks owner and co-founder of Marquis Jet, reminds himself of after having had Goggins as his live-in personal trainer for a month.

Goggins first caught Itzler’s attention at a 100-mile race. Itzler was running as part of a relay and Goggins was running the full length solo. According to Itzler, Goggins had broken all the small bones in his feet and had kidney failure during the race.
