Most of us are familiar with the 80/20 rule. But what the heck is the 40% rule?
The 40% Rule is the idea that when our mind is telling us to quit, that our body has actually only used up 40% of it's potential. Think of this in terms of a workout; how many times have we been deep in a long grinder and that doubt begins to creep into the back of our head? -- Crossfit Invictus
Our mind is responsible for protecting our body, and it does that so well it over-protects us sometimes. The built-in warning system inside of us kicks in and why wouldn't we listen? Giving-up is easy.
It is believed that David Goggins, a retired Navy SEAL, and ultramarathon runner, first coined the term "40% rule". According to the author Som Bathla of "The Power of Self-Discipline", this claim is backed up by researches.
To resist giving up, it takes more than physical strength. It requires mental toughness. And entrepreneurs need that, too. Workouts not only pumps oxygen to our brain, it also gives us the chance to practice the 40% rule and train our mental toughness. No more excuses to skip workouts regardless how busy the schedule is.
