Wise men don't need advice. Fools won't take it.

Benjamin Franklin may have been onto something when he said, "Wise men don't need advice. Fools won't take it". It is one thing to be confident in ones wisdom it's another to think one is so wise they have nothing left to learn. Friend, if you had nothing left to learn your energy would be vibrating so high you would not even need to be of this world anymore. So lets just say if your still here then you have lot's to learn!
The universe teaches us in every single thing that plays out in front of us. There are hidden messages in numbers, geometry, words spoken off in the distance, the birds singing, the annoying dog barking at the house next door. There is never a given moment when you can not walk away after something is brought to your awareness with out taking away more knowledge. But wait. You have constant opportunities to gain knowledge! Why can't you just go to the library and gain more knowledge? Maybe study all the famous guru's of the world or live under the word of God and the Bible? Surely you will be a wise man if you study the word of the wise. Right?
You are not a wise one until you let go of your ego, walk in with your wisdom with your bare feet, and live your wisdom and not push it upon others and even then you are never so wise that you can not gain more wisdom. As humans we use very little of our brains. If we have all this space available we must have plenty to learn! So the next time you think you are more right than the next person maybe you should stop and question your wisdom because yes you may possibly be correct in this situation but more than likely you still have plenty you can learn from it and it may just be that you merely need to learn to let go of your ego.
