If Weber had to choose the single best piece of business advice he's received from the billionaire investor, it would be to focus on building the strongest possible brand.
"It sounds cliched, but this long-term thinking about really building a brand of strength is what makes Berkshire so unique, and him so unique," Weber says.
"You can measure brand strength and you can track business results, and they're not always in sync. We all like growth, and bigger businesses are more valuable than smaller ones, but the key is, the brand has to be stronger at the end of the year than at the beginning. And Warren means it. He really means it."
While a lot of people understand the value of a strong brand, not a lot of people understand how brands are built, Weber says.
"Brands are built over years and years and years. And they're built on trust," the Brooks CEO says. "If we're going to do something meaningful here, you can't change who you are every three years. You build a brand over literally a decade, or two or three."
