The first thing that came to mind for me is Facebook. I remember I attempted probably a half dozen times to cancel Facebook before I finally did. Every time I’d get to one of the handful of screens that make you click through and then change my mind or just simply deactivate it for a little bit. I would tell myself that it has all my photos on there or the friends that I’d never talk to but maybe would one day if i wanted to. The exit cost was huge.
