Where does the ambition go?

We're about 1 week into summer, and I wasted most of the morning THINKING about getting things picked up and cleaned around the house. The thing about summer is... I feel like I have time to do it another time... later this week... later today! My time is not pushed to get anything done. Then days pass and there is still nothing clean! My diet has taken a hit too! I've slacked off a bit on the no sweets, and I feel it! So... in the next couple of days I've got to figure out how I can keep motivated to get things done and keep my little fingers off the food.... Who has ideas?!?!?
