1. Start a business if you want to get rich: you can also start a business if you want to lose a lot of money. I lost nearly $100k that would have otherwise gone into my retirement trying to start a business. Most businesses fail. So think starting a business should be seen as a high-risk investment.
2. You can't get rich on a salary: My wife and I have never made six-figure salaries. We are in our mid-40s and we will be breaking $1 million in retirement savings this year if the economy stays stable. We did this by maxing out our 401k contributions since our 20s.
Becoming a millionaire is a lot of hard work, but if the recommendations in this article are too extreme I've always appreciated Elizabeth Warren's advice of 50/30/20: 50% of spending on necessities, 30% on fun, and 20% on savings. Using this a guide, I've been able to tell when I need to downsize my spending and I've been able to spend on fun without feeling guilty.
