     Don't make sudden changes. Start slowly, by waking just 15 to 30 minutes earlier than usual. Get used to this for a few days. Then cut back another 15 minutes. Do this gradually until you get to your goal time.

Sleep earlier. You might be used to staying up late, perhaps watching TV or surfing the Internet. However, you just might fall asleep much sooner than you think.

     Put your alarm away from your bed. You have to get up out of bed to shut it off. By then, you're up.

Now you just have to stay up.

     Go out of the bedroom as soon as you shut off the alarm. Don't find an excuse to go back to bed. My

habit is to force myself into the bathroom. By the time I've washed my hand, and the toilet of course, and

looked at my ugly face in the mirror, I'm awake enough to face the day.

     Allow yourself to sleep in once in a while, as long as it's not a regular thing. I do it maybe once a week or so.

     Make it a reward. At first you're forcing yourself to do something hard, but if you do something

pleasurable as part of your morning routine, soon you will look forward to waking up early. My reward used to be to make a hot cup of coffee for myself and read a book. Now I look outside (or better yet, get

outside!) and watch the sky turn light. It's beautiful. It's now my favorite time of day.

Getting up early is a reward in itself for me and so will it be for you.
