Western minded People in the past have barated me for saying this...
Saying 'it makes people think your dumb' or 'it makes people think you dont beleive in the things you say...'

What do I know?

Is a Daoist lesson and saying....
My Daoist Sifus Shun and Po would say it a lot....
Its said with humour and to be seen as a reminder...
That however much you know, there is ALWAYS MUCH MORE TO LEARN!
That if you let your ego get in the way, it will try to convince you... THAT YOU ALREADY KNOW EVERYTHING AND THERE IS NOTHING YOU CAN LEARN FROM ANYONE...
So,

What do I know

Is there to give you a little smack with a wet fish!
And remind you that you are always a student in this game of life...
Even Sifu/Teacher can learn from the student....
Nature will always be ready to teach you something if you are open, willing and humble enough to listen...
So,
Dont Worry
Let go...
And go with the flow...
Have fun!
And what ever you want to beleive...
Is true!
;-)
But remember...
What do I know?
:-P
