"Millionaires have shared three themes related to removing yourself from the trap of working to live: Creating margin in their lifestyle to allow for career moves, particularly significant ones (e.g. living off of savings while starting a business); exploring career opportunities while generating revenue from a traditional job (i.e. moonlighting); and making a move to self-employment," she wrote in her book.
Here's a closer look at each of those themes:
1. Spend below your means
Many of the millionaires Stanley Fallaw interviewed stressed the freedom that comes with spending below their means.
"The freedom translates into opportunities to make career changes that provide either (a) more time and flexibility to pursue efforts outside of work, and/or (b) the potential for increase in revenue," she wrote.
She added: "Spending above your means, spending instead of saving for retirement, spending in anticipation of becoming wealthy makes you a slave to the paycheck, even with a stellar level of income."
Chris Reining, who retired early at age 37 as a self-made millionaire, previously told Business Insider that being rich and becoming financially independent isn't about a paycheck or how much money you have it's about how much you spend and living below your means.
"Getting rich, and staying rich, is overwhelmingly a game of living below your means," he said. "If you can do that you'll enjoy a freedom that people living rich will never experience."
2. Find a side hustle
Moonlighting, or taking on a side hustle, has been favored by many millionaires it's a good way to explore options while remaining employed full-time, according to Stanley Fallaw. But making a side hustle successful "requires resources, both time and money, to develop and maintain," she wrote.
"Those who are able to create multiple opportunities to generate revenue, who can translate hobbies into income-producing activities, will be successful at becoming millionaires next door in the future," she added.
It's possible to transform a side job into a full-time career if you have the hunger, execution, decisiveness, and perseverance for it, Susie Moore, a high-performance coach, consultant, and author, previously wrote in an article for Business Insider .
It can certainly help you get there faster Business Insider recently spoke to a handful of people who have taken on side hustles, and they earned anywhere from an extra $1,000 to $30,000 a year. Invest that money and the power of compound interest will lead to wealth.
3. Become self-employed
Those who are financially independent can grow their wealth even more by working for themselves.
The self-employed millionaire next door of tomorrow is likely to take risks to transform their resources into something of value, according to Stanley Fallow (42% of the millionaires she spoke with are self-employed).
"The potential payoff for those career risks, specifically for the risk associated with starting one's own business, is the ability to generate revenue, more revenue often than would be possible working for someone else," she wrote.
Stanley Fallow found in her latest survey that self-employed millionaires have more than 1.5 times the median income of those who work for others. Their actual net worth minus their expected net worth is double that of those who work for others, on average, she wrote.
Stanley Fallow said investing in one's own business is a hallmark of the economically successful, as long as they have the right strengths like perseverance and resilience to survive the journey.
