When you got your driver's license you made a promise. Do you remember it? You promised to drive safely, obey all the traffic laws and respect the rights of other drivers. Most of us break this promise within days of making it.
If you'd like to enjoy a radical sense of ease and peace of mind, drive the speed limit this week.
Granted, you may need to leave a couple of minutes earlier. And you'll be driving slower (and legally) than everyone else, becoming the target of various hand gestures from stressed out drivers. (That was you last week!)
