.... and (btw), when talking gambling on the stock market, allowance (prior recognition of the possibility) for bad management (along with a plethora of other factors) is part of the equation. So fair enough, whinge about bad management but the blame for losing one's money always rests with one, and that is the gambler they-self.

Pretty self evident IMO.

[Same for a winner, recognise the factors which led to the win, but always congratulate oneself for being a smart arse, because it was you who done it. Winners are grinners, losers can please themselves, but usually resort to acrimony toward anybody but themselves (esp, in my experience of HC of complainants).]
