“Shewing to the generation to come.”  What can you show them?  Are there pitfalls that one can avoid if they follow your advice?  Are there mountains another can summit by walking in your example?  You, yourself, have learned some stuff along the way.  Why not leave something along the pathway of this journey (Hansel and Gretel), for another to follow?  Don’t hide it, show it!  Don’t keep it all for yourself, mentor another.  Give them a good foundation to start off on.
