Not squeamish about swiping things from other web pages, I came across this quote:

“Eat a live frog first thing in the morning and nothing worse will happen to you the rest of the day.”
— Mark Twain

The point was that you should do the thing you most DON'T want to do first - in this case it was exercise. Not sure I can use this to motivate on my weight loss quest although if I truly ate a live frog I'd be so grossed out that I wouldn't want to eat for the rest of the day....hmmmm gotta go buy some frogs!!
