Week days its just a routine, I've been at this job for almost four years and the quarter to six alarm is just normal, if the alarm doesn't go off I wake up anyway. I've been cycle commuting in total for over thirty years, riding my bike to work is just part of life's routine, though for the last eighteen months I have been running a car as well as the bikes, if its raining when I get up these days I reach for the car keys instead of the bike. On a Sunday its different, if the weathers bad I just go back to sleep, its a non essential bike ride I can have a lie in and treat it as a rest Sunday then ride the next Sunday if the weather has improved.
Try and work out a routine for the mornings and stick to it, after a while it will become normal.
