By making sure that I enter at the front of the metro rather than at the back, I figure that I speed up my walk to work by the time it takes to stroll a full metro length, say maybe forty-five seconds. That's a pretty significant win when you think about it.
However, by having to get there in the first place from where I am initially standing, I have to invest at least a full metro length to make it to the front of the metro. Let's avoid fooling ourselves from something that makes perfect sense, and subtract the forty-five seconds, please.
This so-called illusion therefore effectively cancels out any long-term investments by first incurring short-term debt which is never won back. Net result is thus zero. Entering the front or the back does not make any difference.
