Discipline Is Destiny summary

Tired of your surroundings? Hop on a plane. Dissatisfied at work? Change jobs. Crave pizza? Order it. Have an opinion? Share it. In much of today’s world, people can do and access almost anything they want at the snap of a finger. And yet, with all this freedom, so many of us are so unhappy. What are we doing wrong?

President Eisenhower famously said that freedom is the “opportunity for self-discipline.” And this is the key. Unless we have temperance, or the virtue of self-discipline, all of these things that supposedly liberate us – technology, privilege, success – will only leave us spiraling without direction or purpose. In other words, access without self-restraint leads to imbalance and dysfunction.

Let’s dive in a little deeper. We all have a lower and higher self – those inner voices constantly vying for our attention. It’s Hercules’s choice between vice and virtue. The side that gives up versus the side that tries. The part that clings to excess and chaos versus the part that seeks balance.

Self-discipline is the ability to keep your lower self in check and strengthen your higher self. It involves working hard, practicing good habits, enduring challenges, setting boundaries, and turning a blind eye to temptations. In short, it’s about living a life guided by principles, moderation, and determination.

You might be thinking, Hell, no. Not for me. Self-discipline? More like self-deprivation! Maybe you celebrate or even envy people who take the easy path. You might think they’re having more fun or getting ahead faster. But look more closely, and you’ll realize that all that glitters isn’t gold. Take greed, for instance. It means you’re always on the prowl for more – and so never really enjoy everything you currently have. And not realizing your full potential? That’s a state which breeds pain, misery, and self-loathing.

Self-discipline isn’t about depriving yourself – in fact, it’s the opposite. It’s about using control to open up a world of opportunity.

Let’s return to Eisenhower for a moment. When he was young, he learned a Bible verse that echoed a lesson taught by the Stoic philosopher Seneca: “Most powerful is he who has himself in his own power.” Eisenhower carried this lesson throughout a long, unglamorous military career, all the way into his appointment to Supreme Commander of the Allied Forces in World War II – and then into his role as the 34th US president. His enormous success didn’t result from force; instead, he was powerful in his restraint and ability to persuade, compromise, and practice patience. 

It’s true that it takes courage to cultivate self-discipline. But embracing this lifestyle will likely make you more successful. And, more importantly, it’ll make you great – no matter what happens. 

In the next sections, we’ll explore exactly how to manifest self-discipline physically, mentally, and spiritually. First up? The body.
