I certainly hate the word. There is someone I know who talks about "mindfulness" all the time, especially before he walks into an open pit. Anxious people have minds that are "full" of junk and would be better off making them empty.
I've also met certain people who claim to practice "mindfulness" but in reality just lack reflection. (I'm not saying anything about mindfulness per se.)
Please reread the comment you just replied to.
