Wisdom and the Proverbs

I am reading through the book of Proverbs now and much of the book extols the virtues of wisdom. But what is wisdom? Is it knowing the mind of God? Is it learning from our experiences. Is it only valuable if it comes from God, or is there some value in human wisdom? I know that wisdom from God is valuable and that is ultimately what I seek. I guess that my prayer is that I can discern when I am relying on my own faulty wisdom. Unfortunately for me that is something I struggle with on a regular basis.
