Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath: James 1:19
Become a good listener. Good listeners earn the respect of others and also earn the right to be heard. People tend to ignore the advice of anyone that does not listen to them. An added benefit to listening is the knowledge and insight you will gain. Listening, like learning, is an art that must be developed. Again, become a good listener.
