I know that intellectual charity is a virtue one should practice, but I can't resist to think that the text is mainly in favor of very dangerous gambling with the added argument that "sometimes, you can win, like I did".
On balance I believe people who are impulsive catapult themselves into worse outcomes. This article could be dangerous advice for people with poor impulse control. I'd phrase the most workable advice as something like, 'If you are loss-averse and tend to stick at things, blowing up your life to do something new could be a good choice'.
