3. When describing the soldier, Shakespeare describes reputation as a "bubble." What's his message to the reader here?

The “reputation,” for which a young man is eager to venture his life, is actually bubble-like; implying that it's not going to last long. It's not considered prudent to endanger one's life for something that's trivial or insubstantial. Life's is too valuable to be lost for an insignificant cause.
