Aged wisdom

I spent most of my day with our local director of missions.  One thing I've learned as I've grown older is that I should pay more attention to the wisdom of those who are still older than me.  There is so much we can glean by simply listening and learning.  I often wish I could have spent time really talking to my grandfather.  He passed away when I was around 12 or so.  I didn't know how much I could have learned from him until I was in my twenties.  Luckily, there are still plenty of people who have experienced so much more than me.  It would be idiotic of me now to not take advantage of the wealth of knowledge they possess.  Why should I have to learn from the same mistakes that others learned from long ago?  Maybe humility grows along with wisdom as we grow older.  Maybe I just keep realizing how much wisdom I really lack.  Hopefully that is the key to gaining wisdom, simply realizing you lack it in the first place.
