My advice is living on 50% of income, and saving. It doesn’t matter if income comes from business or a job. Even if you don’t think index funds will grow, which is going against 100+ years of historical returns, you have to park money somewhere for capital preservation.

After saving one year’s expenses as cash in the bank, where would you park savings for low-risk passive capital preservation? Cash gets destroyed by inflation. Bond yields are too low. The historical track record of 20 years in a good stock index is unbeatable, no matter what year you started.

Where do you keep your savings, right now?

Even if you focus on growing capital by starting a business (what The Millionaire Fastlane recommends), you still have to park the profit somewhere.
