Over the years I have served on many different boards. Occasionally, I'll serve alongside another board member who dominates the conversation, expressing opinions on almost every subject.  

Unfortunately, center-of-attention kinds of people don't usually ask many questions or seek understanding. Instead, they tend to only offer uninformed opinions. 

This means that their input often overlooks important facts. They haven't taken the time to uncover important information that may positively impact their conclusions.  

Furthermore, they consume time that other board members might have used to ask appropriate questions. 

Proverbs 18:2 teaches, "A fool takes no pleasure in understanding, but only in expressing his opinion." 

If you serve on a board, or a team, ask more questions to gain understanding. Spend less time expressing opinions that may inhibit others valuable insight.
