Hannibal the Carthaginian general for example spent nearly 20 years fighting the Romans on their own turf in Italy. He had a string of victories and also suffered incredible losses including the loss of an eye to infection.
Despite that he led his men and was incredibly popular. After laying waste to the Italian countryside for two decades he was reluctantly recalled back to Carthage where he served as a statesman for several more years.
He was then exiled and a price put on his head and he made plans to ally himself with other leaders of the day - honestly his life goes on and on. The guy's resiliency is incredible and he isn't the only one of his age. There are numerous examples of similar people from the history of the time.
I suppose your modern day cases like Musk or Jobs are what we'd think of today. The former's challenges are well documented but the latter had just months to turnaround a sinking Apple and restructure the company before it ran out of money. He'd been through many ups and downs and again displayed a resiliency which is pretty remarkable.
I think that everyone's ability to handle stress varies. What I'd love to know is why some people can suffer incredibly and not only survive but thrive and if there is some way in which we can learn how to suffer the everyday arrows slung our way and bear our burdens better.
