This is a proverb of unknown origin but the point (and irony) of this phrase is that a skilled professional is so busy serving other people that he neglects his own children. I think it goes beyond that and can be applied to anyone who is so focused on work that they can’t see what’s right in front of them.
Are you the cobbler or the children in this scenario?
If you’re the cobbler, ask yourself if all of this work is worth everything else you’re missing out on. If you’re the children, tell your father to give you a damn pair of shoes already.
Maybe you’re both the cobbler and the children. How much of your own life are you neglecting because you’re so consumed by work? Is it worth it?
