Life is hard. Painful for a lot of it. But that doesn’t mean don’t live a meaningful life.
I’d argue all the difficulty is what makes anyone’s efforts meaningful. If there were zero strife, what would accomplishment look like?
Philosophers have stated this far better than I can, since the beginning of recorded history in Sumer.
And if it seems things are tough today, read “Hard Times” by Studs Terkel.
(I’ve had chronic, frequently debilitating pain for 30 years. For the last year, just walking/standing has been very difficult. My grandparent’s generation had it even harder - I remember, and understand better now).
