You know what's a great business? One where the margins are totally in your favor and your customers don't do math.

For example, the lottery.

With no big winners over the weekend, expect to see a lot about Mega Millions and Powerball over the next few days, since their combined jackpots will exceed $2 billion in the next drawings on Tuesday and Wednesday.

If it seems like the dollar figures are bigger now than they were a few years ago, that's because both lotteries have decided to trade longer odds for higher prizes.

It's paying off. The miniscule odds of winning are even more miniscule, but the number of tickets sold went up.

Somebody will likely win this week. Maybe more than one person.

There's a 99.9999997 percent chance it won't be you, but those odds won't stop millions of people from buying tickets. Nice business.

And now, Elon Musk

Mark your calendar for December 10. That's when Elon Musk says The Boring Company will open its first tunnel in Los Angeles, with free rides for the public the following day. He says that target date is "real time," not "Elon time." Your guess is as good as anyone's. (Minda Zetlin,

'When you fail, I don't have time to coddle you'

That's what Brené Brown, the author and research professor with the fourth-most viewed TED talk of all time, advises bosses to tell their employees. It's about setting the expectation that you understand they'll fail sometimes, and it's not that big a deal. She spoke at the Inc. 5000 conference in San Antonio last week. (Kevin J. Ryan,

A free way to avoid people driving while intoxicated

Self-driving car company has an interesting way to gather data and get some good publicity: free rides to and from after Dallas Cowboys games for fans who might have had a few too many beers. The program, which also includes free transportation to other local landmarks, is funded by the city of Arlington and will last a year. (Peter Holley, The Washington Post)

Extremely inspiring

A 6-year-old girl who was diagnosed with acute lymphoblastic leukemia came up with a more comfortable dress for kids who have to undergo chemotherapy. Now she and her mother, working with volunteers, have made hundreds of dresses for other young cancer patients. (Cathy Janek, The Beacon-News)

What could possibly go wrong?

Of all the things the world needs, clearly the RMS Titanic II--a 21st Century replica the original Titanic--is at the top of the list. The $500 million ship, originally announced six years ago but delayed for myriad reasons, will now apparently be ready in time to make its maiden voyage in 2022. (AnneMarie McCarthy, Lonely Planet)
