Strength of character is not about how loud or quiet a person is. We would not be saying this were it not for the fact that this is often misunderstood. It is not uncommon for someone with a strong personality to feel that a quieter, softer type of person is “not their equal”. In many cases, they form this view because they undervalue the inner strength the person possesses.
It is a major error of judgment to imagine that true strength of character can be measured based on how boisterous or outwardly dynamic a person is. If you have an extroverted personality, you may do well with someone with a lower signature on the radar – if only you were able to appreciate what that kind of person really is.
