Entrepreneurship Can Ruin Your Life

Here is an interesting story about a couple that started a coffee shop and… well let's just say it wasn't what they expected.

The failure of a small cafe is not a question of competence. It is a sad given. The logistics of a food establishment that seats between 20 and 25 people (which roughly corresponds to the definition of "cozy") are such that the place will stay afloat-barely-as long as its owners spend all of their time on the job. There is a golden rule, long cherished by restaurateurs, for determining whether a business is viable. Rent should take up no more than 25 percent of your revenue, another 25 percent should go toward payroll, and 35 percent should go toward the product. The remaining 15 percent is what you take home. There's an even more elegant version of that rule: Make your rent in four days to be profitable, a week to break even. If you haven't hit the latter mark in a month, close.

That's why you have to love the game. Starting a business so you can have more free time, or because you want to be rich, is a sure path to bankruptcy.
