Even though this video is from almost 10 years ago – the message still rings true today.

CNBC’s talk show “The Big Idea with Donny Deutsch”, which ended in 2008, talked to successful businessmen and women about their histories and philosophies. Many of these talksended up providing some sound advice for would-be entrepreneurs.

One show in particular had Robert Greenberg (the CEO of Sketchers) discusses what distinguishes successful businesses from unsuccessful ventures.  Greenberg’s answer is simple – Persistence – “If you start down any road, there’s always going to be a left or right turn. You just can’t see it from the starting line,” Greenberg says. “Just don’t ever stop trying.”
