Why is everyone obsessed with “be grateful every day just because you're alive”?

Life is literally bullshit, it's cruel and

and hard.

Just accept it and it becomes easier and even fun

I don’t need motivation or support, it’s broken from the beginning.

I do all this sport, diet, and healthy stuff, reading books, sometimes I’m even nice to people, and all the other crap, just to suffer less while living.
