The story is told of a young man who wished to marry a farmer's beautiful daughter. He went to the farmer to ask his permission. The farmer looked him over and responded, "Son, go stand out in that field and I'm going to
release three bulls, one at a time. If you can catch the tail of any one of the three bulls, you can marry my daughter."

The young man stood in the pasture awaiting the first bull. The barn door opened and out ran the biggest, meanest looking bull he had ever seen. He decided that one of the next bulls had to be a better choice than this one, so he ran over to the side and let the bull pass through the pasture out the back gate. The barn door opened again. Unbelievable. He had never seen anything so big and fierce in his life. It stood - pawing the ground, grunting, slinging slobber - as it eyed him. Whatever the next bull was like, it had to be a better choice than this one. He ran to the fence and let the bull pass through the pasture, out the back gate.
The door opened a third time. A smile came across his face. This was the weakest, scrawniest little bull he had ever seen. This one was his bull. As the bull came running by, he positioned himself just right and jumped at just the exact moment. He grabbed... but the bull had no tail!

Life is full of opportunities. Some will be easy to take advantage of, some will be difficult. But once we let them pass (often in hope of something better), those opportunities may never again be available.
