An operator, not a theorist.
Most advice comes from people who never ran a business. I've done the owner's work: payroll, suppliers, fixing breakdowns, carrying the weight. I know the gap between a spreadsheet and a real decision.
So I work on performance. I find the money because I've found it in my own businesses. If I can't, you don't pay. I'd rather say so early than bill you to learn that.
"I'd rather earn my fee from your result than charge you for my time."
