If you have ever driven with a back-seat driver, you know how annoying it can
be. That person - who isn't driving, and may not ever drive at all - will
tell you exactly how to proceed, and what you are doing wrong. They will
criticize everything from the route you are taking, to the point at which you
turn on your blinker, to your speed, to the condition of the vehicle. If you
are dealing with someone like this now in your personal life, it can be
extremely frustrating. This person has a lot of criticism, but they are not
driving - you are. Tune them out, and you'll have a better ride.
如果你曾經有在開車時遇到愛指導駕駛的乘客，你就會知道這會是多麼的煩人。
那個不開車的人(也許從來沒開過車)，會告訴你如何行進，告訴你做錯了什麼。
他們會批評你採取的路線、打方向燈的點、你的速度，所有車輛的一切。
如果你現在生活中正有這種人，這可能會是讓人非常沮喪。
這個人有很多的批判，但是他們不駕駛，而你要開。
把他們驅離，你將會有更好的旅程。
