Judgment you can borrow.
I take on a handful of engagements a year with owner-operated businesses. The work lives where value is quietly made or lost: pricing power and unit economics, working capital, hiring and incentives, and the operating cadence that turns a strategy into a normal Tuesday.
Most advice describes your problem back to you at a markup. Mine starts where the textbook ends, because I've sat in the owner's seat: the constraint is rarely the idea. It's cash conversion, incentives, and follow-through.
