And when stock markets crash, it's our nature to wait it out on the sidelines. So, it's tempting to sell "before things get any worse."
Buffett loves it when stock prices drop since it creates opportunities to buy at a discount. This is why Buffett was extremely active in the stock market in the years immediately following the 2008-09 financial crisis.
Buffett embraces discounts on his favorite stocks. As he says, "Opportunities come infrequently. When it rains gold, put out the bucket, not the thimble."
5. Approach your investments with a long-term mindset.
One of the most important Warren Buffett quotes on investing that you can take in is, "If you aren't willing to own a stock for 10 years, don't even think about owning it for 10 minutes."
He doesn't choose stocks just because he thinks their prices are going to rise this week, this month, or even this year. Buffett buys stocks because he wants to own those businesses for the long term. To be clear, in practice, Buffett sells stocks frequently, but he approaches most of his investments with the mindset of owning them forever.
It's also worth noting that if you can't get into a "forever" mentality with your stocks, Buffett argues one of the best investments most people can make is a set-it-and-forget-it investment, such as an S&P 500 index fund.
