I've heard that if you want to make money in the stock market, you need to be very careful about the stocks you buy. Is this true?

It depends on what you mean by “careful.”  If you’re talking about investing with a long-term horizon and trying to maximize your returns, then yes, it is important to be cautious when buying stocks. If you are just looking for short-term gains or trading stocks as a hobby, then it may not be necessary to be so cautious.
