How do I cope when my job only serves company profit?

You traced the thread of your work all the way out, and it ended at the company's profit and nothing you personally care about. You are good at helping a balance sheet, and you cannot find the place where any of it connects to something you would value outside those walls. That is a lonely thing to notice, and an honest one. Here is a gentler way to look at it. Not all meaning has to come from the mission on the letterhead. A paycheck that supports the people you love is not nothing. The way you treat a struggling coworker is not nothing. The care you put into the work itself, the craft of doing it well, is a value even when the end result only feeds a spreadsheet. The company's purpose does not have to be your purpose for your hours to hold some worth. Still, if the gap keeps aching, listen to it. Find one thread in your day that connects to something you actually value, whether it is a person you help, a skill you are building, or the life your income makes possible, and lean into it. And begin, quietly, to picture work that would end somewhere you care about. You do not have to leap. You just have to stop pretending the balance sheet is enough.
