Once upon a time there was an astronomer. His habit was to go out at night and observe the stars in the hope of finding a new star.
One night, he kept gazing at the stars and walking along. He walked out of the town gates and came to a field outside town. Totally absorbed in his gazing up and looking at the stars, he was not aware of the ground he was walking on.
He fell down into a deep hole in the ground. As he lay inside groaning a passerby herd his groans and came to the edge of the hole to help him.
He got the astronomer out and after hearing how he had got himself into the hole the passerby said,
How do you hope to discover what is up in the sky, when you are not even capable of seeing what is under your nose?
Many people whilst following their dreams are incapable of facing up to reality.
