Today, as with so many days, I found myself stuck in a traffic jam, and I thought I’d share my little trick for keeping calm when it seems like you are creeping along(缓慢行进).
The key to understand is that traffic jams don’t take as long as they seem to. It’s just that when we are in a hurry, and think we should be moving, but time appears to pass more than it does. To really show this, the next time you are stopped at a light that always seems to take forever to change, try to do something with your phone, your laptop, whatever you have available, and watch how much briefer the light seems.
When you enter a jam on the highway, reset your trip plan and care the time. Then, when you clear the jam, and are normally on your way again, care the distance of the jam, and the time it took to get through it. For my experience today, it took me 6 minutes to go 2 miles. Now, it happens to be mathematically convenient that your average speed on the highway is about 60 mph, or a mile per minute. So to estimate what time the jam actually cost you, just take your traffic jam passing time, and subtract（减去） the distance covered, which we know is a good estimate of the time it would have taken with no traffic jam. In my case, all that added up to 6-2="4" minutes.
Do this for every jam you are subjected to every time and watch how much less stressful they become once you understand how little time you are really losing.
