Your business should have a solid chance at profitability -- but it should also suit your particular skills and strengths.

If you want to work for yourself, but don't have a particular business in mind, you're probably wondering what kind of business you should start. Fortunately, the answer is always the same: Pick a venture you know intimately, and then research it some more.

Know the Ins and Outs of the Business

Don't fall into the trap of starting a particular business just because someone tells you, "It's a sure thing." Potential customers will part with their hard-earned money only if you convince them that they're getting their money's worth, so you'll need to know what you're doing, no matter what the task.

Choosing a Business You Know

Starting a business in which you already have experience has many advantages: You can use your knowledge about the industry, your training and skills, and your network of contacts who might help you find financing, suppliers, and customers.
