"A wise man will hear, and will increase learning; and a man of understanding shall attain unto wise counsels:"

                            -Proverbs 1:5 

Read the book of Proverbs, and you will find countless verses just like this one: verses that talk about the importance of listening to the advice of other people. Solomon says in this passage of Scripture that a man of understanding will receive wise counsel. Sadly, in today's society, people who think they are wise tend to use that as an excuse to reject advice of any kind, thinking they don't need it. However, Solomon addresses that kind of outlook in Proverbs 9:9,

"Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning."

Taking the advice of other people doesn't mean that we are dumb. It means that we are wise, and have a desire in our hearts to be "yet wiser." If we think that we are beyond needing instruction, that is not a sign of wisdom, but a sign of pride.

"When pride cometh, then cometh shame: but with the lowly is wisdom." 

                        -Proverbs 11:2

And while it is important to seek good advice, we must remember the words of David is Psalm 1:1,

"Blessed is the man that walketh not in the counsel of the ungodly..."

We should seek godly advice from godly people, knowing that "...out of the abundance of the heart the mouth speaketh." (Matthew 12:34) If a person lives an ungodly life, chances are their advice will also be ungodly.
