Good approach, but it's time-bound. How do you find meaning after your kids leave the nest?
That’s why religions appeared, to have timeless meaning, and values. But we threw them out as superstitious, not understanding their purpose
Or get a hobby. Up to you
If you want to put a carrot in front of yourself that can work a bit, but those pursuits are wonderful but not without it's troubles. Kids get sick, friends & family die, we get sick, we fail and much more. And in the end, we know when we are tricking ourselves.
You can experience meaning quite easily & daily without depending on tricks like that; but yeah the way of chasing external stimuli till our death is indeed the Western rational way.
