I have an alarm clock on my bedside table which I set to go off every morning. Just in case.
The truth is...it has never gone off.
Never! Why? Because I wake up--naturally--about 10 minutes before the set time, every single day! Always have.
Did I mention that I get up at 4:30 each morning?
Yeah...I just wake up.
(Ask Allison how much fun this is for her when we are on vacation together!)
