Looking for a new sales associate? Go full-on nerd and try the “37% Rule,” which basically says that when you need to screen a range of options in a limited amount of time — be they candidates for a job or potential romantic partners — it’s a weird mathematical truth that the best time to make a decision is when you’ve looked at 37 percent of those options. (If none is right, pick the next one that is better than the first 37 percent.) According to an article in Lecture Notes In Economics And Mathematical Systems, this approach can be applied to just about any such sequential scenario — from choosing a mate, to a new store location.

Thinking of Liquidating? Think: Wilkerson

When Peter Reines, owner of Reines Jewelers in Charlottesville, VA, decided it was time to turn over the “reins” of his 45-year-old business to Jessica and Kevin Rogers, he chose Wilkerson to run his liquidation sale. It was, he says, the best way to maximize the return on his decades-long investment in fine jewelry. Now, with new owners at the helm, Reines can relax knowing that the sale was a success, and his new life is financially secure. And he’s glad he partnered with Wilkerson for this once-in-a-lifetime opportunity. “There’s just no way one person or company could run a sale the way we did,” he says.
