Invest at least 20% to 40% of the money you make each month. My preferable choice is to invest money in index funds. Keep investing on a monthly basis and never check how much money you got in the index fund. Let them be there untouched for at least five to ten years. Even with a recession, you will continue to buy into the stock market and get an even better buy-in price for the stocks. Don’t worry about a stock crash, it will just give you a better return in the end when the market turns bullish.
Fun fact: If you invested in a Dow Jones index fund in 2008, you would have seen a 221% increase after we INCLUDE inflation!
