Do you sometimes feel that no matter how much wealth you accumulate, toys you own, friendships you make or physical and mental mountains you conquer, you’re still at the end of the day unfulfilled – with a gnawing deep down inside that something is “still missing” or that you’re meant for something greater than what you’re doing right now? You’re not alone. That loss of direction, purpose and deep, fulfilling meaning is absent in the lives of some of the most successful or fit people you’ll ever meet.

As an author, speaker and consultant in the realms of health, fitness, nutrition and body and brain optimization, Ben Greenfield is perhaps most well-known for his teachings on biohacking, fitness, muscle gain, fat loss, nutrition, supplements, longevity, cognition and beyond. But for much of his life, he did not focus upon building his spiritual muscles in the same way that he prioritized physical disciplines such as caring for his metabolic health, growing his physical muscles, or tending to the neurons in his brain.

However, after years of pursuing body and brain optimization, Ben grew to realize that the relatively self-obsessed or carnal pursuits of a lower body fat percentage, finding the perfect diet, climbing your own personal Mount Everest of a triathlon, Spartan race, or CrossFit competition, learning a host of new languages and musical instruments, increasing the health of your blood and biomarkers or “reversing the aging process” are all ultimately unfulfilling, and can often leave one standing at the top of the mountain of physical and mental achievement, yet feeling disappointed and extremely empty inside despite having accomplished what might appear to the world to be lofty and admirable goals.

See, most of us inherently know that caring for our soul is important, but we somehow shove it to the side because, let’s face it: life gets busy and it just seems far more practical and immediately useful to go hit the gym rather than sitting cross-legged on the floor meditating and praying, spending an extra five minutes in bed in the morning gratitude journaling, or prioritizing relationships during a long and joyful family dinner. Fact is, Ben personally spent about 20 years of my life, up until he was in his mid-30’s, barely tending to his spirit—until he realized that his own unhappiness and constant striving for the next big physical, mental, business and personal achievement and obstacle to overcome was simply leaving his spirit even more shriveled, shrunken, unfit and neglected, and leaving him unfulfilled, unhappy and unable to fully love others or to make a maximum, purpose-filled impact with his life.

Over the past several years, as Ben has repeatedly witnessed in both himself and others the ultimate unfulfillment of a sole focus upon carnal, fleshly pursuits, and as he’s observed great thinkers and philosophers while continually seeking wisdom, he’s become increasingly convinced that caring for one’s spirit is as important—no, actually far more important—than caring for one’s body and brain.

Perhaps nowhere is this “soul importance” more eloquently stated than Matthew 16:26: “For what profit is it to a man if he gains the whole world, and loses his own soul?” How about you? Have you gained the world yet left your soul behind? Do you feel like that most important part of you – your soul – is shrunken, neglected and unfit? Do you crave for more meaning, purpose and fulfillment in your life?
