This isn't a "don't borrow money to invest lesson". It's a... - you should diversify lesson - don't chase yield lesson - pick good stocks/funds lesson You didn't go wrong with leverage. You went wrong with what you used it on. I know people who bought cruises and airlines during covid because they were cheap, and then sold at a loss because it wasn't recovering. Like you, that's not a lesson on investing, its a lesson on what they bought. You bought specific equities and it didn't work out. I'm buying specific equities and the results show it's working out. The only difference is what we bought.
