You already know the feeling, even if you have never named it. The raise comes through, and for a few weeks the world looks brighter. Then it doesn't. The new phone thrills you until it is just the phone. The holiday you saved a year for fades into photographs you rarely open. You got the thing. The lift it gave you drained away faster than you expected, and there you are, scanning for the next thing.
Three thousand years ago, a man who owned more than anyone alive watched this happen in himself and wrote it down.
"All things are wearisome, more than one can say. The eye never has enough of seeing, nor the ear its fill of hearing" (Ecclesiastes 1:8).
Solomon had everything. Wealth, power, every pleasure he could name, and he tells us in the next chapter that he denied himself nothing his eyes wanted (Ecclesiastes 2:10). The verdict from the top of the mountain was not satisfaction. It was weariness. The eye never has enough. There is always one more thing to see, and seeing it never fills you.
Psychologists have a name for what Solomon noticed. They call it the hedonic treadmill.
The pattern is simple and well documented. Something good happens, a promotion, a purchase, a win, and your brain rewards you with a surge of pleasure. But humans adapt to almost anything, and quickly. Within a startlingly short time, the new normal becomes simply normal. The car is just the car you drive. The salary is just the number in the account. Your sense of wellbeing drifts back down to roughly where it sat before, and the spike you were chasing is gone.
So you reach for something bigger. A larger purchase, a higher rung, a stronger hit, because last time's dose no longer registers. You run harder to feel what a smaller effort used to give you. And the treadmill, by design, keeps the finish line exactly the same distance away no matter how fast you go.
You are sprinting, and the scenery never changes. That is not a flaw in how hard you are running. It is the machine working as built.
This is what Solomon meant by a word he uses again and again in Ecclesiastes: hebel. We translate it "meaningless," but the picture underneath is breath, or vapour. Something you can see and feel for a moment before it thins into nothing. The thrill of the new thing is real while it lasts. Then it evaporates, and you are holding the empty wrapper, wondering why it did not hold.
Here is the part the treadmill hides from you. The problem was never that you had not yet found the right purchase. The hunger is not waiting for the correct object to arrive and switch it off. The hunger is the condition itself.
A child opens the longed-for toy and is delighted, briefly, then asks for the bigger version. You smile at that, but you do the same with the car, the house, the title, the next experience, just with a longer gap between the asking. Solomon, who could afford any answer money offered, tried them all and called the whole chase a running after wind (Ecclesiastes 2:11). You cannot grasp it. You only exhaust yourself reaching.
Which means stepping off the treadmill is not about wanting less, gritting your teeth, learning to be content with the phone you have. Willpower on a treadmill just means jogging instead of sprinting. You are still going nowhere.
The way off is not a smaller appetite. It is a different hunger, aimed at something that does not thin into vapour the moment you reach it.
Solomon spends most of Ecclesiastes describing life lived, in his phrase, "under the sun," as though the visible world is all there is. Under that sky, the treadmill is the only honest description of things, and he refuses to pretend otherwise. But the book is quietly pointing past its own horizon the whole time. The restlessness you feel, the way no acquired thing ever stays satisfying, is not only a curse. It is a clue. You were built with a hunger that nothing under the sun was ever sized to fill, which suggests it was never meant to be filled there.
You can stop running now. Not because you have finally caught the thing, but because the One worth wanting was never on the treadmill with you. The spike fades. The vapour clears. What remains, what does not decay back to baseline, is not a possession at all. It is being held by something that does not evaporate.
The eye never has enough of seeing. The soul, it turns out, was looking for someone all along.
