I've struggled with forgetfulness my whole life (sorry wife, and dad, and mom, and...everybody).  So occasionally I need to write myself reminders and leave them in placed where I'll be sure to see them (taped to my car's speedometer works quite well).  I never thought of leaving reminders here, though...

It's so perfectly obvious!  Maybe that's why it's so easy to overlook.  Just grab a dry-erase marker, and leave yourself some messages before bed...
