As the Buddha said, "there's no such thing as noble suffering".
It's possible for people to fall into this, where they exclusively focus on concentration meditation (like the breath) that leads to a kind of narrow-mindedness. It's also difficult because there are just so many books out there for people to read, that it's tough to know exactly what people are reading and suggesting to others, and some of the new-agey type literature ('think positive!') can possibly be harmful.
There are many reputable sources (historically and currently) that can say that the purpose is NOT to suppress your thoughts, even though this can be a common misconception about meditation practice.
I'm a creative person, and I've gotten some really great ideas for projects or solved some things at work by just letting my mind bounce around from idea to idea, so I'm hesitant to replace that with a still mind. Although every once in awhile I need to relax or calm down and meditation helps with that.
