Early to bed, early to rise makes Liz...dull

I've tried it for four weeks now. It seemed like a good idea at the start of the new school year. Getting up at 6.30am, walking the dog in the park. Back home by 7am ready to get the children out of bed and into school uniforms and into the office for 8.45. Four weeks was long enough. Getting up early is so depressing and walking the dog at that time even more grim. I began seeing the same people at the same point on my route EVERY DAY! Aaaagh. The lady in blue wellingtons with the black and white collie, Elsie in her wheelchair taking her King Charles Spaniel past the bowling green, the man jogging in an adidas tracksuit with a black labrador. It was so depressing. I just can't do it anymore. I cannot do the same thing day after day that early without it seeming like a pointless groundhog day. Even worse, by 9pm I'm exhausted and have to go to bed early. All too horrible. I tried to get up even earlier but that was impossible, vary my route - but I soon bumped into new 'park regulars'. Now I know that some people spend their whole lives doing the same thing over and over again. They may find it comforting but I find it profoundly depressing. Standing there throwing the skimmer disk so monotonously, so early in the morning is very wrong for my constitution. I'm genetically hard-wired to get up late. The dog will have to wait for her walk, I'm staying in bed longer.
