Why do I keep failing at the same thing I resolve to change?

The short answer Because you keep framing it as a battle to be won, and it’s a path to be kept. You shovel the snow off the path and by morning it’s white again—and that isn’t you failing to defeat winter; it’s just what snow does. The resolution you ‘broke’ didn’t fall like a wall; it drifted over like a path, the way paths do. Stop trying to win it once and for all, and start taking this morning’s turn at keeping it clear—because the day you needed it won-forever is the day you quit.

The longer answer

You shovel the path in the morning—clear it right down to the stone, neat edges, a good job—and it snows again in the afternoon, and by next morning the path is white and gone as though you’d never touched it. You could stand there, leaning on the shovel, and take it as a defeat: all that work, undone overnight, the path exactly as buried as before you started. What was the point?

But nobody feels that way about snow, and the reason is instructive. You don’t shovel the path to defeat winter. Winter is not a thing that can be defeated; it will snow again tomorrow and the day after and all season, and no morning’s shovelling was ever going to be the morning that wins. You shovel to keep the path clear today—so that today you can walk to the gate—knowing full well you’ll shovel it again tomorrow, and the whole arrangement is fine, and not the slightest bit demoralizing, because you never mistook it for a war.

Now put your recurring resolution beside the snow. The thing you keep ‘failing’ at—the temper, the drink, the phone, whatever bed keeps going green—you’ve been framing it as a wall to knock down once and stand triumphant on the rubble of. So when it comes back, as it always does, you read it as total defeat: I broke it, I failed, I’m back where I started, what’s the point. But it didn’t come back like a defeated wall rebuilding itself. It came back like snow. Like a path drifting over. Like every maintenance there ever was.

Which means you haven’t failed the way you think. You cleared it once; it snowed again; that’s not the collapse of the project—that is the project. The work was never to win the thing forever and be done. The work is this morning’s shovelling, and tomorrow’s, each one keeping the path clear for one more day, none final, all of them enough. The day you decide you can only bear it if it stays won is the day the next snowfall breaks you and you quit. The day you accept it’s kept-daily, not won-once, is the day you can actually keep at it for good.

Whether the snow ever stops—whether some winters end, and some resolutions finally hold without tending—I can’t promise. Most don’t. But the path can be clear this morning, and that was always the whole of the job. It may be so. It may not.
