Marcus Lemonis has some tough-love advice.
The star of "The Profit," who has invested $35 million into failing businesses in an attempt to turn them around, has seen just about everything. And it isn't pretty.
"The one piece of advice that I would give every entrepreneur in America: that owning a business isn't for everybody," Lemonis told CNBC.
"It takes a different kind of person," he said. "It takes somebody with a thick skin and a tough stomach. It's not a glamorous job."
