If You Don’t Know Your Numbers, You Can’t Possibly Master Marketing.
By Rich Harshaw
Three-thirds of everything worthwhile I learned about business I learned from my dad.
As a longtime real estate guy, he taught me at a young age the value of knowing your numbers. He dropped me off for my freshman year at BYU and gave me (or should I say, ‘bestowed’ upon me) the handheld calculator I still use 25+ years later—an HP-12C financial.
I don’t mean I still use the same kind—I mean I still use the exact same machine my dad gave me all those years ago, with my name and SSN scratched on the back. If you know anything about financial calculators, you know they calculate everything “backwards” and confuse the heck out of uninitiated users. Always good for a laugh.
Regardless of the kind of calculating device you’re most comfortable with, hear me loud and clear—your calculator is your most important marketing tool.
