According to "The Millionaire Next Door" by Thomas J. Stanley, Ph.D and William D. Danko, Ph.D, the average millionaire is married with three children. The wives of these millionaires are good budgeters and most often described as even more frugal than their husbands. Interestingly, according to Stanley and Danko's survey, half of these wives do no work outside the home and of those who do, they are most likely teachers.

One upside of only marrying once is avoiding the costs of divorce and of subsequent weddings. The cost of a divorce depends on many factors including income, attorney fees, court fees, and the assets a couple has and how they are divided. The average wedding cost in the United States in 2010, according to The Wedding Report.com, was $24,070.

2. Live off One Income

One of the advantages of having a life partner is the potential to pull in two incomes. If you are able, consider structuring your set expenses based on only one income, and save what comes in from the other income. Doing so strengthens your financial position in two ways: In case of an emergency or if one partner loses their job, you will not only have less set expenses to cover, but you will also have built up your net worth as a safety measure.

According to The Millionaire Next Door, "self-employed people make up less than 20% of the workers in America but account for two-thirds of the millionaires." The book goes on to list an average of 45 to 55 hours spent working per week, so by no means is this the self-employed fantasy of playing golf while your business grows.

The idea of the "right" career can encompass a myriad of factors. Ideally, this would be a career you enjoy, otherwise you likely won't be putting in the dedication required to be successful. The right career would also coincide with overall working trends, or at least not work directly against them. For example, starting a career in typewriter manufacturing may be something you are passionate about, but it would likely suffer due to the current technological trends.

4. Put Your Money in Appreciating Assets

The end result? These people put a financial priority on assets that will make them money, from their homes to their businesses.

5. Don't Live the Millionaire Lifestyle

The Bottom Line

Becoming a millionaire is easier than ever. While this is a dream that will take work and discipline to achieve, it isn't as far out of reach as you might think. Be smart with your money and before you know it, you'll be able to count yourself among the world's wealthier citizens.
