Well, I know that if you want to get to sleep earlier, it's not good to be looking at a TV or computer screen, as the amount of light can signal your body that it's not time to sleep yet. So maybe doing something in low light the 30 minutes to 1 hour before bed would make it better to sleep earlier (I know, hard to pry yourself from the Internet, but for good sleep it is a must!)
Also, it helps to have a regular sleep schedule, to go to bed and wake up at the same times. Some people can have a little more leeway than others, but for me I need to keep a rigid sleep schedule, or I lose all kinds of sleep.
