Some naif is about to discover the cold hard facts of life. Lesson to be learned: shut up!

Teen earns $35,000 plowing snow during Seattle’s snow storm and, foolishly, brags about it.

Eighteen-year-old David Holston owns a landscaping and snow plowing company in Coeur d’Alene, Idaho. He was visiting his mom in the Seattle area for her birthday, and he brought along his plowing equipment thanks to a friend’s suggestion.

Holston says he put an ad on Craigslist when the storm started, and his phone rang constantly.

By comparison, most websites like Homeadvisor.com put the average snow removal hourly cost at about $110, ranging from as low as $30 an hour to as high as $400 an hour.

Holston says his customers didn’t seem to mind the price but were just glad to have someone to plow.

David, now that the authorities are on to you, they’re going the suck you dry: 15% social security tax, right off the top, then state and federal income tax, then sales tax and, this being Seattle, probably a number of fingers will be put into the pie, all demanding a slice.

You run a cash business: keep it that way, and keep your success off the Internet — the enemy is watching.
