I cannot live a life of "what if". Have you ever read C. S. Lewis' The Lion, the Witch, and the Wardrobe? If you have, you will remember Aslan saying something to the order of, "you can't ask what if".
Another saying, particularly used in the 70's, was "if Life gives you lemons, make Lemonade."
We get one life, and we should live it to the best of our abilities. Our lives are what we make of them, so. . .
no, I don't want to trade lives with anyone, past or present. I am not rich or famous, but, for the most part, I am happy. I don't mean joyous every minute, but peacefully happy most of the time. I have everything I need and lots of what I want. . .
and I have love. . .the love of God and the love of my husband and family and friends. For this I am very thankful!
