Let me start by being a little silly. From Ogden Nash:  
  Money won't buy happiness but its funny 
  Have you ever tried to buy it without money?

How to be the bridge? By conscious intent. I do earnestly think so, by conscious intent. One could call it grace on command and I am sure it is rarely easy. And I am regularly amazed by it.  Conscious intent may not change everything, but can anything change without it?
This is highly personal but it is increasingly consistent with the most remarkable findings about wave-particle uncertainty.  To observe or not observe makes a difference. Intention makes even more. Together, perhaps all the difference. 
 What cause for sadness but separation, our separateness. And what a lie that we are separate. In our essence, at our most essential, we do really seem to be ever emerging from the cusp of undetermined possibility, becoming manifest, determined chiefly by convention or expectation. But consciousness, especially when not hidebound by self-consciousness, yields other possibilities. Intention helps pick which ones become manifest. 

Sometimes when I want to remind myself of this, I say to myself,  god-AM,  and sometimes people think I'm swearing and I suppose I am.

Neil Simon's "Bridge over Troubled Waters" was perhaps my generations version of this song with differences. A big difference is that Simon's song was an offer as opposed as a request. Different times. 

To those who have been a hope, a bridge, a silent escort, please don't try to give yourself all the credit. I've got some to give you too.

Well, OK, my two cents worth. Got change?
Cheers
