Morning Workouts

I start my Summer Reading Program at the library in two weeks. This is always my busiest time of year. It is non-stop from the moment I arrive until time to leave...and most days I don't get out on time. I am thinking about changing a couple of my workouts a week to mornings during the summer. If I workout in the morning, I get it out of the way and won't talk myself into "skipping just one night." I usually workout in the mornings a few times a month because of evening programs at the library, and I enjoy working out in the morning. What I don't enjoy is leaving my house so early in the morning and showering at the gym. (I never feel clean after I shower at the gym.) My Mom doesn't live far from my gym so I could go to her house once school gets out for summer, but that is a bit of a hassle too. I guess what I need from you guys is tips and advise on motivating myself for these morning workouts :)
