It's not impossible to give up a bad habit. And for those who succeed, there's often a desire to rise to more challenges. 'If I can give up that,' they think, 'maybe I can give up this too'. Some people end up becoming obsessed with abstinence; they spend all their time looking for more things to stop doing, and encouraging other folk to do the same. In the end, though, there's a risk that they'll have no sources of pleasure left. Although you need to distance yourself from something now, there's no need to let go of what brings you joy.
