Doing reasonably well investing in stocks, is very, very easy.
Buy an index fund, preferably over time, so you end up owing good businesses at a reasonable average price, and that is all you have to do .You don’t need to look at the prices of the stocks you own from week-to-week, or month-to-month, or even year-to-year. If you own a cross-section of American businesses, and you don’t get excited (and buy) just at the very top, and if you buy in over time, you are going to do well.
