) -- How do you find that right product or service upon which to build a business? There's no single answer, but there are a number of guideposts and guardrails to help entrepreneurs and small businesses prepare for success.

The key is passion for and knowledge of your product or service -- and the market.

It helps to be first with a market-making idea, like Post-It notes from

. However, those kinds of Eureka moments are the exception and certainly not the rule.

You need not be first. Take the late Ray Kroc, for example. He wasn't the first with the idea to serve food quickly, but he did transform a small venture called

into a worldwide model of efficiency. The key message here: You don't have to be first if you can figure out how to do it better.

When it comes to making money on a product or service, I'm a proponent of opting for what I call "must have vs. nice to have." We all spend money on nice-to-have products and services. That's especially true during the holiday season, which can be a bonanza for businesses that start out in the nice-to-have category. But some of the best, most recession-proof and built-to-last businesses evolve by providing something in the must-have category.

One example that comes to mind is my Atlanta-based neighbor,

Newell Rubbermaid

, and its brands such as Rubbermaid, Sharpie, Grayco, Lenox, Levolor, Paper Mate and Parker. The company keeps its thumb on the pulse of ever-changing consumer and commercial markets, and has been innovating, acquiring and re-inventing itself for more than 100 years, touching millions of people every day with a must-have portfolio of products that includes writing instruments and power-tool accessories to beauty and baby products.

Newell Rubbermaid's slogan, "brands that matter," is one of the better descriptors around. It's a great differentiator, too. In particular, I like that the concept is ingrained into the company's values.

How many must-have companies in addition to Newell Rubbermaid can say they sell into more than 90 countries, and that more than 90% of U.S. households use at least one of their products? I'm all ears because, as an investment, I'd bet those companies are likely to be a cut above a stock that rises and falls on the nice-to-have.
