It's not arbitrary that God created us with two ears and only one mouth.
The Bible tells us in James 1:19 to be "...quick to listen, slow to speak...."
The study note for that verse further clarifies:
'When we talk too much and listen too little, we communicate to others that we think our ideas are much more important than theirs. James wisely advises us to reverse this process.
Put a mental stopwatch on your conversations and keep track of how much you talk and how much you listen.
When people talk with you, do they feel that their viewpoints and ideas have value?'
Winners talk less and listen more, and show respect for others' ideas.
