What I have found is that if my Monday is great I am in for a terrific week. How do you make sure you have a great Monday? Make it great. You are responsible for how your day turns out. Here's how you can make your day great.
1) Make a list of everything you would like to accomplish.
2) Pick the 6 biggest things on your list. Go for quality over quantity. If 3 will take you all week, then stick with 3 as long as they are the most important things on your list
3) With uncompromising discipline stick to your list.
4) Avoid distractions and these time wasters:
-moving on to easier, but less important tasks
-attempting too much at once. Complete one task then move on to the next.
-inability to say "no"
-lack of self discipline
Try it out this week. I believe you will feel better about your week and will enjoy your holiday weekend much more knowing that the "big" stuff has already been handled.
