Get a head start the day and evening before. I make Sunday my preparation for the new week and pamper day making it easier to greet the new week. Instead of having a journal filled with jobs not completed from the previous week, I will have spent time over the weekend ticking off those things I have accomplished and set new goals, action plans, and to-do lists for the coming week.
I do a mini wardrobe sort and plan on Sunday making it faster and easier to keep appointments during the new week. 
The worst thing about Mondays for most people is having to rush or being tired due to strenuous activities on Sunday. Keep Sunday as a time to regroup your thoughts, plan your coming week, make exercise one of incidental activity as you tidy your surroundings and prepare for the week ahead, and strive to be in bad on time, or even a little earlier than usual as a catch up on any recent late nights.
