Dear Dr. Boli: I want to start my own business, but I read somewhere that most new businesses fail in the first six months. Well, that sucks. I’ve decided to start a business that can’t possibly fail. All I need to know is what kind of business it should be. —Sincerely, A 17-Year-Old Who’s, Like, Sick of the Daily Grind.

Dear Sir or Madam: Dr. Boli would advise you to start a business selling shipping supplies on line. Every order will have to be shipped, of course, and each shipment will require shipping supplies. And from whom will those supplies be ordered? You can see how this business very quickly becomes completely self-sustaining.
