I hadn’t really planned on taking a trip this time of year, and yet I found myself packing rather hurriedly. I knew in   36   that this trip was going to be unpleasant.

I’m talking about my annual Guilt Trip. I got tickers to fly there on WISH – I – HAD’ airlines. I   37   my baggage all the way, which was weighted down with a thousand   38   of ‘what might have been’. No one greeted me at the ‘Regret City’ International Airport.

As I   39   into the Last Resort Hotel, I noticed to miss that great   41   occasion.

Many leading citizens went there. First, there was the ‘Should – Have - Done’ family.   42   came the ‘I – Wish’ family. Of course, the ‘Opportunities’ family, ‘Missed and Lost’, surely made an   43  . They each had a dad story to share. ‘It’s – Their - Fault’ treated us with stories about   44  things had failed in his life, and each story was applauded by ‘Don’t – Blame - Me’ and ‘I – Couldn’t – Help – It.’

To make a long   45   short, I became very depressed at the party   46  .

But as I though about all the stories of failures   47  from the past, it occurred to me that all of this trip and ‘pity party’ could have been cancelled by ME!

I truly realized that I didn’t have to be there to be   48  . One thing kept going through my mind – I can’t change yesterday, but I   49   have the power to make today a wonderful day. Knowing this, I left ‘Regret City’ immediately. Am I sorry for   50  I’ve made in the past? YES! But there is no physical way to undo them.

So, if you’re planning a trip to ‘Regret City’, please cancel all your reservations now.   51  , take a trip to a placed called ‘Starting Again’, which I like so much that I’ve made it my   52   residence. My neighbors, the ‘I – Forgive - Myselfs’ and the ‘New - Starts’ are so very helpful.

By the way, you don’t have to carry   53   heavy baggage, because the load is lifted from your shoulders   54   arrival. Surely you’ll find this great town – it’s in your own heart. Look me up if you’re ready for a (n)   55   changer in your life. I live on ‘I – CAN – DO – IT ’ Street.
