1. Get Enough Sleep
If you’re exhausted and bleary-eyed during your morning commute, it may be much more difficult to stay level-headed. Additionally, if you work a long day on little sleep, you may be feeling even worse in the afternoon.
Be sure to get at least seven hours (eight is preferable) of quality sleep per night, even if it means changing up your evening schedule so that you can hit the sack sooner. If you start each day feeling well rested, it becomes much easier and more natural to calm yourself down should you feel driving anger taking hold.
