How to overcome the hurdle of waking up early for a sunrise?

Don't go to bed in the first place and, instead, shoot stars and wait for the Aurora Borealis all night long (for nothing) and finish your photo trip with a sunrise over Aasleagh Falls and the Erriff River in Connemara. Unfortunately my expectations were a lot higher than the actual sunrise was, with a lot of mist and water spray on lower ground and little or no clouds in the sky. And adding to the insult I had less than 30 minutes to get ready for an 8 hour shift in the gallery. I am dead!! Need some sleep after being awake for over 36 hours straight.

I am too old for this stuff!!
