Now this is the case, leveraging much on a bet and putting your expectations to conquer you. I know emotions can't be eliminated but Can be reduced. When one gamble, gamble based on your risk tolerance and allow the bet decide understand the fact that you nothing is predictable and be ready to accept any outcome.
If you don't trust yourself, don't go in. Forget the odds, or potential winnings, set limits. The truth comes when the gambler accept he can't control the outcome and is ready to lose his money and accept any outcome regardless. So before you bet ask yourself if you are ready to lose that money?
When we take actions based on emotion the later outcome is always regret. Dust off yourself and move on. Don't allow expectations consume you, always consider the risk before the win.
Overconfidence is your keyword here. That's the issue with "secured" or "guaranteed" bets; there's no such thing, and I believe we've all encountered something similar that was completely unexpected. The truth is, there are no guarantees when you're betting. I've been burned in the past; it's reasonable to feel mad or frustrated, but how well you control your reaction is up to you. Going as far as breaking stuff is a problematic and abusive behavior, which may have a deeper meaning as well, perhaps meaning a violent person or one who's unable to manage their feelings and themselves. And now what? $1.000 lost, and who knows how much more to replace the TV—something completely unnecessary.
You are on point but I would rather label this stupidity rather than overconfidence, the two are not the same thing even though they still fit in this context, only that one outweighs the other. This is what I can only resort to in this context as I think of it over and over again, because that guy could not afford to lose the money, nevertheless, he went on to gamble it, so that's stupid. Gambling is not as bad as many think about it but the gamblers engaging in it are the unwise ones doing unspeakable things that make people label gambling bad. Gambling is never a do-or-die thing, so why try to believe that it is your last hope?
This is the way those who are risking what they can't afford to lose think and behave, but this must stop to avoid persistent issues for them. We should endeavour to gamble what we can afford to lose, manage our psychology in gambling and also have good management towards the portfolio. But it is sad that many people know all these but will still go ahead to gamble by overlooking all the warnings. This can only happen because of stupidity and nothing else.
