Summer frustrations

Ah, summer. No teaching. Small College Town is peaceful and quiet except for the few students around taking summer classes and coming for freshman orientation. My days are generally unstructured and full of possibilities. And that is my major problem. I ALWAYS have trouble motivating and being productive in the summer. I think the endless stream of days ahead of me just lulls me into a sense of infinite time. "I can do that tomorrow! Or next week! Wouldn't it be better to just clean out this closet or watch a movie?" And that is just during the time that D is still in school. She has her last day on Wednesday, then I am really screwed. Not that she needs constant attention or supervision, but a day-long stretch of uninterrupted research time is just not feasible (OK- I'm just making excuses). But I want to do things with her, while we are both out of school, so I am distracted by making plans for those things. Maybe, I'm just lazy. Who knows, but summer is a time that I never seem to be productive and it's a shame.

What are your strategies for staying focused in the summer? I could use some ideas, because after seven years in this job, I still can't figure it out!
