For the last fourteen years, I’ve worked across the street from Boston’s main train station. In addition to the local commuter rail and subway trains, there are many Amtrak trains that leave throughout the day, and they’re often stacked up patiently waiting when I pass through in the mornings. I hear the announcements, destinations I have never been, and the ATM is right there, and I could easily buy a ticket and go. Maybe somewhere close even, so I can get back home in the same day, would anyone even notice?
I consider it an amazing bit of discipline that I've never done it.
