MOMMY, MOMMY! I am so worried.
Mommy said: Remember the Mother Goose Rhyme.

My dear child, do not worry about what you can not change because you can not change it anyway, and do not worry about what you can change because you can change it if you try. Let me tell you a story. The Little Engine that Could

A little railroad engine was about a station yard to pull a few cars on and off the switches. One morning a long Circus train asked a large engine in the roundhouse to take it over the hill "I can't; that is too much a pull for me," said the great engine. Then the train asked another engine, and another, only to hear excuses and be refused. At last in desperation the train asked the little switch engine to draw it up the grade and down on the other side. "I think I can," puffed the little locomotive, and put itself in front of the great heavy Circus train.

As is went on the little engine kept bravely puffing faster and faster, "I think I can, I think I can, I think I can." Then as it near the top of the grade, that had so discouraged the larger engines, it went more slowly, but still kept saying, "I--think--I--can, I--think--I--can." It reached the top by a surge of brave effort, saving the Circus, and then went on down the grade, repeating to itself, "I thought I could, I thought I could."

To think of hard things and say, "I can't" is sure to mean it will not be done." To refuse to be daunted and insist on saying, "I think I can," is to make sure of being able to say triumphantly by and by, "I thought I could, I knew I could."

And the child chanted I Think I Can, I Think I Can, I Think I Can, Mommy, how do you know so much.
That's What My Mommy Taught me Dear, and the child drifted off into a Peaceful Slumber.
