Over the past decade I have heard people talk about their rising stress levels. More information, more responsibility and the same 24 hours a day to get it all in and done, respectively. What I don’t see many people doing is distinguishing the unhealthy stress from the healthy stress. Much of what positively motivates us is stress not its absence. As Barry Lenson writes in his book, Good Stress, Bad Stress [ http://goo.gl/3zDTK0 ], there are two types of psychological stressors. He characterizes them as positive or negative using some practical criteria so I thought I’d share them.
