The 1 Investing Habit That Separates Stock Market Millionaires From Everyone Else

The key habit separating stock market millionaires from others is consistency—regularly investing over long periods, particularly in index funds like the S&P 500. Research shows 769,000 401(k) millionaires have invested for an average of 25 years. A 25-year-old investing $100 weekly could accumulate $2.4 million by retirement through compound growth, requiring emotional discipline to maintain investments during market downturns.
