I usually drive to work a couple of days a week (and commute the rest). Slow traffic is a big problem trying to get through Stockholm in rush hour and standing still in traffic jams can be incredibly frustrating and not very good for the hart.
But I found a cure for my self and it is: Audio books!
Listening to a good book really keeps me a lot calmer. So that’s my tip to you, if you’re expiriencing similar feelings for traffic jams. Right now I’m listening trough David Eddings The Mallorean.
