Are there any types of businesses I should avoid?

Businesses that use hazardous materials, make edible goods, care for children, sell alcohol, or build or repair structures, vehicles, or other items of value come with inherent risks. Unless you are prepared to start a corporation or limited liability company and can afford adequate liability insurance (which can be pricey), you may be better off working for one of these businesses rather than starting your own.

In addition, there are some types of businesses that are particularly vulnerable to competition, including restaurants, bookstores, video rental stores, movie theaters, grocery stores, and Internet and computer service providers. But these businesses sometimes do survive, especially if they can fill a niche market and develop a loyal following.
