What's the point of life if you don't want kids?

I've been thinking a lot about this, and honestly, I can't figure it out. If you don’t want kids, then what’s the purpose of life? It just feels like an endless cycle of working a job that takes up most of your time, with barely any free time left. And even when you do get free time, there’s almost nothing to do.

I get that some people find purpose in hobbies, travel, or personal growth, but at the end of the day, it all seems kind of meaningless. If life is just working until you die, then what’s the point? How do people without kids find meaning?

Note: I don't want kids myself that's why I'm asking.
