                                   I love Fridays. And so I celebrate Fridays.

    After dropping my son off at school I head to Starbucks to pick up a coffee treat or another. Then instead of driving straight home I take a long route through the most beautiful roads I can find. I see footballs being passed on lawns, hamburgers being thrown on grill(烤架), and parties everywhere swinging into action.____

    The o0ther day I came out from the doctor's office happy over a positive prognosis(预断). Seeing the signs of spring around me-flowers, birds, sunshine, I was suddenly ready to celebrate. ____

    My mind rebelled. “What are you doing? It's Tuesday! Coffee treats are reserved for Fridays!”____ Why should Fridays be any more special than any other day of the week? Why waste six days while waiting to celebrate the seventh? Minutes later I was walking back to my car with a big smile on my face and a coffee in my hand.

    A small victory, to be sure, but it's also an accurate example of how many of us live our lives. We're waiting for conditions to be right before we allow ourselves to enjoy our time here on earth. Maybe when we finally graduate from college and get a job, it will be time to celebrate, or perhaps when our babies are old enough to be in school all day. We'll celebrate when the car is paid off, or enjoy life when we're finally able to retire. ____ What if we moved a little of that “Friday feeling” into our rainy-day Mondays, our dull Tuesday and our mid-week Wednesdays? ____

A. You must spend more time achieving it.

B. Surely our lives would be much happier as a result.

C. It seems as if the whole world is celebrating Friday!

D. But suddenly I realize how ridiculous that line of thinking was!

E. Find an excuse to celebrate and start sending out hose invitations.

F. I headed for the coffee bar that was located just around the corner.

G. And in that waiting we waste so much of life and happiness that can be found in our Todays.
