And a female guide came to me as I was stranded upon a lake on scattered floating debris last night.  I had gotten myself out there by carefully adventuring from one piece of scattered debris to the next—the pieces, seemingly of a shipwreck, were fairly contiguous though not precisely continuous.  So my footing 'out' was consciously tentative and studied. 

However, after venturing a good distance out,  the danger of drowning suddenly came upon me as the lake whipped up with gale force winds and the debris I was navigating started to toss and flip.

"Don't look back, go on," is all she said.  So, trusting, I began.  And my footing 'in'—which I was envisioning not as 'back' to shore but 'on' with life—was nothing less than spontaneously instinctive, true, and non-reflecting.

I am here!  ha.  Thanks to my water guide, I have, perhaps, finally mastered the esoteric art of 'not looking back'.
