It sometimes feels like having bad habits is an inescapable part of being human. You know certain vices are doing you harm, you know you should stop them before too long, you know they’re often not conducive to a healthy and happy life.
Of course, not all habits are equally damaging, and not all people are as committed to a bad habits as, say, someone who smokes a pack of cigarettes everyday. My point is that most people have or have had a habit that they’d rather kick than keep.
