I tell people like you and me to take an alarm and place it near someone else's room in your house. For example, a parent or an older sibling. Set that alarm to go off at 5 am and piss them off. Set YOUR alarm for 4:50. When you wake up, make sure to remember that you have this extra alarm set and that if you don't turn it off you'll have to answer questions about why it's set up, and deal with their anger. That's a good motivator.

Or, leave your alarm clock across the room so that you have to get out of bed.

Or, if you take any sort of medication, take it during your WBTBs to motivate you to get out of bed. Or your laundry for the next day (procrastination AND laziness, woot)

Or, if you have computer speakers and an ipod, hook an ipod (with alarm set) to your speakers and set this on the highest volume to some sort of crazy song that starts off loud and fast. Set another alarm 5-10 minutes before the ipod so that you're motivated to get up and turn off the ipod.

Things like that
