I worked for many years busting my but to try to move up the corporate ladder and succeed. In a good year I might have received a 5% pay increase vs the normal 1-3%. Then I realized everyone else was making essentially the same and not working hard, so all that work was really just for 1-2% more than them. I was frugal, I budgeted I saved money, i did all the stuff recommended here and it all helped it really did, but man was it a slow way to go.
Finally I started a side business and it took a couple of years and I was finally able to quit my job and become a millionaire three years later, much quicker than the path I had been on.
Anyway, the whole point I'm making is that owning a business or investing in real estate can really jump start you if you are on a quest to become a millionaire.
