At 50 years of age I wonder... is it easier to look forward or behind? Is it easier to go back and fix things or to just start anew and see where experience will take you? Can my life long mantra of "No regrets" continue to serve me now that the number of days left is undoubtedly less than days passed. Should I mend those fences and broken bridges or forge new paths as I always have without a backwards glance?  At what point should I admit that what I have artfully tried to portray as tracks of forward momentum have in fact all along been nothing more than splattering from the centrifugal force of my life, through no control of my own?
I can't believe I am losing sleep over this.  I suppose that in itself is my answer.
May as well put on the coffee.  It's going to be a long day.
