Heh. Reminds me of a friend who keeps "investing" which is handpicking stocks and hoping that they succeed. Now he has a group of friends and they spend most of their time playing this stupid game of trying to pick a winner. Which sounds like a waste of both money and time.
This advice is how you end up like my friend: he's got thousands of dollars in high interest credit card debt and a porfolio full of stocks. Like, dude, you're paying 30% interest to gamble on stocks and he thinks he's being prudent because "investing."
When people say "save" or "invest" without context, people end up borrowing at high interest in order to do so. I saw a guy on Reddit with like $30,000 in credit card debt and $20,000 in a savings account.
