Listen to the radio, smile at the other aggravated drivers, if it's bumper to bumper with very little movement.....I might SNEAK in a text or phone call....but NEVER when traffic gets moving! Think happy thoughts.....decide what I'll do as soon as I finally get home.
I always carry books, magazines and crossword puzzles in my car....to bring into waiting rooms with me. So, I might thumb through some of those..
Use the handy wipes in my car, to wipe down the dash board and tidy up a little...
Check out my hair and make up and give myself a "touch up!" LOL.
Think about topics to write about? That might be a wise choice for all of us writers, don't you think?
Basically, I do whatever it takes to make the time fly and keep my attitude positive!
