I have never had difficulty waking up early. But that doesn't mean I like to.
Here is a great way to start of your day on a positive note. Its very easy, requires less than 5 seconds of your time. You don't need to buy anything. All you need is a mirror, and yourself!
When you wake up early in the morning, go to your bathroom. Look into the mirror, and say out loud "I'm (or your name_'s) going to have a GREAT day today". Don't just think it... actually SAY IT OUT LOUD (in a positive way). Say it with a smile on your face, with you head high, loudly. and that my friends....is the BEST way to start your day
Try it, and please let me know if it works
