The Hard Truth That Flips “Do What You Love” Advice on Its Head — And the Marine-Backed Path to Real Passion, Purpose, and Unstoppable Drive
“In order to love what you are doing, you must first be doing what you truly love.” ~ KJ Carleo
This isn’t a feel-good slogan or a recycled piece of motivational wallpaper. It’s a hard truth that flips the common advice on its head. Most people chase “do what you love” like it’s a magic bullet that guarantees endless joy and zero struggle. The deeper reality—the one that actually sets you free—is that genuine love for your daily work only ignites when your actions, your career, your hours, and your energy are aligned with what truly lights you up inside. Until that alignment happens, you’re not loving what you’re doing; you’re enduring it.
In Cast Your Light, I wrote it plainly in the chapter on enthusiasm: “In order to truly love what you do, you must first be doing what you truly love.” It sounds elementary, but it is quite a profound statement. You need to discover what ignites your passion and keeps it lit. You—and only you—can discover what that is. Passion is the critical ingredient that elevates and sustains your enthusiasm, even during the tough times we all inevitably face. When you love what you do, enthusiasm follows naturally.
Passion isn’t fleeting emotion. It’s the steady fire that makes you wake up with the same excitement you carried to bed the night before. It’s what makes the hard days worth it. Find your bliss—the activity, the mission, the contribution that puts a genuine smile on your face and makes your soul say yes. In Cast Your Light I put it this way: discover what you find easy to talk about for hours, what you lose track of time doing, what you would do even if no one paid you. That is your North Star.
My second book, It Is Up To You, takes this truth deeper into daily practice. One of the 365 meditations reminds us that purpose isn’t something we stumble upon—it’s something we choose and then walk toward with intention. Love becomes the compass. When you set your intention to live from that inner alignment, even ordinary days start to feel sacred. You stop drifting and start building. You stop waiting for the perfect conditions and start moving with quiet, relentless purpose.
Here’s where the rubber meets the road—and why this matters more than ever. Doing what you truly love is not a permanent vacation from difficulty. The brilliant writer Alex Mathers captured it perfectly in his piece “How to actually do what you love and why that matters”:
“You do not have to do what you love, to do what you love.” ~ Alex Mathers
He’s right. The tapestry of any meaningful pursuit is woven with threads you enjoy and threads that test you, stretch you, and sometimes suck the life out of you in the moment. The challenges aren’t bugs in the system—they are the very forge that turns passion into power. The moments that make you want to quit are often the ones that prove you’re on the right path. When your work is rooted in what you truly love, those hard seasons don’t break you; they refine you. They become the raw material of your legacy.
This is exactly why I wrote both books. Cast Your Light was forged in the Marine Corps crucible—250+ years of Honor, Courage, and Commitment taught me that the greatest version of you is only one deliberate 30-inch step away. It Is Up To You is the daily apprenticeship that turns that single step into a lifelong walk: one meditation, one honest choice, one return to intention at a time.
So here’s the question that only you can answer today:
Are you doing what you truly love?
If not, stop waiting for permission. Stop waiting for the fear to disappear. Stop waiting for the “perfect” time, the perfect boss, the perfect economy. Discover it. Name it. Take the step. Align your intention with it. Let your passion fuel the days when enthusiasm runs low. Because when you finally stand in that alignment, something shifts: you stop trying to love what you do. You simply do—and the love follows.
The next chapter is yours to write. Cast your light. It is up to you.
