Stamina might be the most underrated attribute to succeed in life.
You might've watched that Rockie movie where Rockie took on Ivan Drogo; in that fight, Rockie took a pounding. That fight is a great metaphor for what life is really like. It punches us in the face over and over again. And if we have the stamina after a while, it will get tired and give us what we want.
Muhammad Ali beat the heavyweight champ, George Foreman, that way too.
Ali was never favored or supposed to win that match but he built up the stamina. The real-life technique came to be known as Rope-A-Dope.
"Ali provoked .. Foreman to attack and force him back on the ropes. Some observers at the time thought that Ali was being horribly beaten and worried that they might see him get killed in the ring... Ali's preparation for the fight, which involved toughening himself up by allowing his sparring partners to pummel him, contributed to observers' sense that Ali was outmatched. But Ali took advantage and won the match when Foreman became tired from the punches he was delivering."
Stamina works in more than just boxing. While everybody is focused on winning fast, ending it quickly, we can focus on stamina. Just look around; the internet is full of get-rich-quick schemes. Productive hacks. Get fit and in shape quickly and without the gym. Maybe some of these quick schemes work, some of the time, but stamina works all of the time.
This is exactly why stamina is so underrated as the best attribute to success, and all the other stuff about quick results is so overrated.
