I suppose this could be in the water cooler as well but seemed more appropriate here. There it is. Every 30 days (or whatever the schedule is) you have to change your password. The author of this essay used it to send himself a message. Setting an intention if you will to make a change in his life. From simple messages to forgive his ex-wife to self-improvement ideas (sleep before 12, etc) each time he typed his password in he was reminding himself.
I've done this in the past. When I was in school my password reminded me to get cracking so I could get through school and out of it.

What about you? Have you used passwords to remind yourself of your goals? Used them to wish doom and destruction on others? Or just fantasize about new toys and trips?
