I once had the opportunity to talk to a world champion cyclist and the question I asked was, "What's the hardest thing about training?" He replied, "Getting out of bed." He said that once he was up and threw cold water in his face he was OK. He'd get on his bike and GO!
That's the key. Make it a habit. No trying to squeeze an extra 5 minutes' sleep, leap out at the first sound of your alarm and get under the shower. You'll soon get the idea.
Otherwise, may I recommend that you take yourself down to the local blood transfusion service and request a litre of geezer blood. Young people sleep well, geezers do not. Get some of that old blood in your veins and you'll be up early with the rest of us. :)
