Day 4 - Make a List
Here are a couple ideas that can help you get it all done with relatively little stress:
Make a List - Take 30 minutes today and make a list of everything you have to accomplish, regardless of how small and unimportant. Set a goal to complete something from the list every day. Do the little things during lunch or after work and save the big, time-consuming items for the weekend. You will be amazed how many items you can cross of in the next week.
Prioritize Your List - Break your list into "must do", "should do" and "If I have time." Focus your time based on these priorities and it will reduce your need to accomplish everything.
Delegate the Tasks - You don't have to do everything yourself. Consider what tasks you can delegate to your spouse, kids, or friends. Make preparing for the holidays a communal event that brings people together while relieving stress on you. Remember, delegating also includes letting go of how a task gets done. It may not be the way you would do it, but another way may be as good or better.
The holidays are a time to relax and spend time with your family and friends. Keep things simple and don't stress over the little things that don't get done. No one will remember the details, they'll remember how relaxed and loving the holiday was this year.
