It's the classic case of "The cobbler's children have no shoes"! or "The painters house is chipped and fadded". Here is a great explanation on the cobbler.
Origin of the phrase the cobbler's children have no shoes?
Answer:
The essence of this phrase is used to describe the phenomenon where certain 'professionals' in any given area are so busy with work for their clients and their teams that they neglect using their professional skills to help themselves or those closest to them. For example - the painter & decorator who never decorates his own house, the web designer that hasn't finished their website, or the accountant who is late in submitting his own tax return
As for my driveway? Me and the cobbler are in the same boat.
