Re-energized and ready to go!

It's Monday! The day of the week that I have the most patience. The day that my babysitting kids can help me cook, get muddy and make tracks in the kitchen and I take it all in stride. I am not saying I am not patient the rest of the week, but Mondays are by far my best days. Tuesdays, Wednesdays and Thursdays are pretty good days. By Friday, I am ready for that weekend break. My question is this. How do I get Monday's patience on Friday? Is there a trick to this? I do not yell or get noticably aggrevated on Fridays, but I do get short. I would like to give my kids my best five days a week.
