The old anti-censorship line was "No girl was ever seduced by a book."
As much as I oppose censorship, I've always regarded that thought as rather feeble. It denies the impact of literature. Just as many of us are uplifted by what we read, so too may we be brought down via the same activity.
I've gotten to the point where my reading is carefully selected depending on what I want my mood to be. Russian literature can be gloomy (although I still read it) and an Inspector Maigret novel makes me want to sit at a boulevard cafe and wonder about the lives of strangers.
So what do you read when you want to get pumped up and which writers do you avoid?
