I've tried different methods for this
1) Getting fancy coffee at the street vendor-- incentive to leave the house!!!
2) Not keeping breakfast food in the house--
the starvation method...
3) 2 alarm clocks

It's always going to be a pain though, if you're fighting it. The best method for getting out of bed early is always going to be wanting to get out of bed and live life.

When you lie in bed at night (and do try to go to bed early) maybe think about 1 thing you are looking forward to doing the next day.
