I cannot believe that the purpose of life is to be happy. I think the purpose of life is to be useful, to be responsible, to be compassionate. It is, above all to matter, to count, to stand for something, to have made some difference that you lived at all.

Purpose runs deeper than happiness

We live in a culture obsessed with happiness, as if it's the ultimate destination we should all be chasing. But notice how often people who chase happiness most aggressively end up feeling empty. There's something backwards about making contentment your main goal—it's like trying to fall asleep by staring at your pillow. The moment you're checking whether you're happy yet, you've already missed the thing that actually makes life feel full.

What Rosten points to instead is something quieter and more durable: the feeling of mattering. Not in some grand, world-changing way necessarily, but in the small, daily choice to show up responsibly for people who depend on you, to notice when someone needs compassion, to build something that lasts beyond your own comfort. A parent losing sleep to care for a sick child, a teacher staying late to help a struggling student, someone listening carefully when a friend is breaking down—none of these feel "happy" in the moment, yet they're exactly when people feel most alive.

The unexpected part is that usefulness and responsibility actually tend to produce deeper contentment than chasing happiness directly ever does. Purpose makes you resilient. When life gets hard—and it will—having mattered to someone gives you a reason to keep going that's far stronger than any fleeting pleasure.
