I'm sorry to say that you can't just become a morning person. This has been an ongoing argument between my early bird husband, and myself the late owl. We have been married for lots of years, and have never managed to synchronise our body clocks.
You can try and pretend to be an early person, but in my experience it never works that well, if nature intended you to be a night owl, you can't over ride your basic programming.
To cope with that whole morning thing though, and I did work a job for a while where I had to start at 6 am., I recommend:
Get up early every day, whatever time you eventually go to sleep.
It helps to get some exercise first thing, we have an extraordinarily cheerful dog, who loves an early morning walk, and that at least puts a smile on my face.
Take a long shower, use one of the herbal shower gels, that has natural pick me ups in it.
Pretend like you are enjoying the whole experience, force that smile and enthusiasm, who knows you may eventually actually start to enjoy the morning.
My own solution, go farming, calving time works real well for us, I stay up late, to make sure all is well, gives me an excuse to lay in until a respectable time of day, He now has an excuse to go to bed early, and get up at the crack of dawn, to take over the day time shift. Each of us is happy because we are working with our body clock, not against it.
