Fast lane or slow lane?

Life is like driving on the road, whether you are driving on the fast lane or slow lane.
If you are those that love fast and furious, then you will enjoy the speed and race on the lane, and will feel impatient at those slowing you down on the fast lane, and feel torturing if need to be on the slow lane.
If you are those that enjoy slow pace lane, you will feel that those speeding away are missing out the bits and pieces in life, and will feel pressurize if need to switch to the fast lane.
There are also many in-between ones, which cannot figure out whether they like fast lane or slow lane, and instead have the circumstances to judge whether which lane they should be on.
Which one are you?
