I think this is also like the whole "you learn that the stove is hot by touching it once" philosophy, which kinda discounts humans' abilities to learn through second-hand information in my humble opinion! There's a huge amount of literature about people underestimating negative risk to problems, so the assertion seems to be scientifically incorrect. But there is definitely a strain of this in lots of successful business ventures (for better or for worse), so it's probably good advice if you want to make a lot of money! Bonus points for being able to navigate the negative social consequences for being the person with this risk calibration without feeling too guilty about it.
