I gotta say the one thing that motivated me was getting up right at the break of dawn, opening the curtains and getting full sun in my room. I don't know if you sleep in late, but I sleep in late, and I've found that if I just pull myself out of bed and get a nice doze of sun that kinda wakes me up, and cheers me up.
AND when your going to bed at night, think about all the things you'd really like to get accomplished the next day, or the following week. Just lay there and picture yourself doing the things you want completed. That usually gets ya ready for the next day.
Exercise in the morning really helps. Even if you think your so lazy you cant exercise. Just throwing punches left and right, knee kicks, jumping jacks, push-ups and sit ups is all you need to get your heart going and blood pumping when out of bed. Take a glass of water to bed with you, so in the morning the second you wake up, drink some water. Get your mouth washed out like that. It refreshes you a little bit also.
I could probably go on with a few things, let me know if what I said helps at all.
Nature is a powerful force. Those who seek to subdue nature, never do so permanently.
