When I finally achieved a net worth of $250,000, I realized that within a few years I could be a millionaire.
By the time I had a net worth of $500,000, I realized that I was absolutely going to be a multimillionaire.
A few years later, when I became a millionaire, I realized that three million would be fairly easy to achieve.
When I reached three million a few years later, I realized that I could be at five and ten million in no time at all.
The time from five million to ten million was much shorter than the time that it took me to achieve my first $250,000.
Yes, people who make a million can usually increase their wealth fairly easily.
EDITED:
I had a steady income, just an average paying salary. I was living below my means and that allowed me to invest in, and eventually buy, the company that I was hired 20 years earlier to start. Then I was able to pay myself a little more and receive benefits of business ownership on a larger scale.
Any additional income came from various real estate investments.
Today, nearly forty years later, 95% of my net worth can be attributed to real estate.
