"Better to be a strong man with a weak point, than to be a weak man without a strong point. A diamond with a flaw is more valuable that a brick without a flaw"

This quote by William J. H. Boetcker is emphasizing the value of having strengths and weak points. He is recommending that it is much better to have a few strengths and some weaknesses, than to have no strengths and no weak points. He is likewise recommending that having a flaw can be advantageous, as it can make someone more valuable. This is similar to the concept of a diamond with a flaw being better than a brick without a defect. Boetcker is suggesting that having a flaw can make somebody more valuable, as it can be seen as a sign of strength and resilience. He is emphasizing the value of having strengths and weak points, and how having a flaw can be beneficial.
