Strength Can Become Weakness
A person who calls himself frank and candid can very easily find himself becoming tactless and cruel. A person who prides himself on being tactful can find eventually that he has become evasive and deceitful.
A person with firm convictions can become pigheaded. A person who is inclined to be temperate and judicious can sometimes turn into someone with weak convictions and banked fires of resolution . . . Loyalty can lead to fanaticism. Caution can become timidity. Freedom can become license. Confidence can become arrogance. Humility can become servility.
All these are ways in which strength can become weakness.
