Going Back to Go Forward

Sometimes going forward requires going back. I'm loathe to admit it, but my buddy makes a pressing case.
I hate going back. Feels like I don't have what it takes to go forward. Or that I lost my way and have to retrace my steps. But what if I left something I need behind? Wouldn't it be as wise as it would be necessary to retrieve it?
And which is worse, admitting that I'm lost or never arriving at my hoped for destination? How can I have what it takes if I'm not willing to discover its name and go out and get it?
And if any of these things are located somewhere along life's journey where I have already climbed, which of the Ten Commandments asserts, "Thou shalt not tread where thou hast trod before?" Base camps are not revisited because of failure, but because of the demands of the trek.
