I did say that nothing is wrong in trying to recover from a loss, but the thing is, gamblers must learn to do it responsibly, I say this because, even in business, people lose, and because of that loss, they are forced, or they force themselves rather, to work harder in other to recover that money which they have lost, so they can return their business to being in profit again.
Same thing can apply to gambling even though I understand that gambling cant and shouldn't be compared to a business since gambling is not a money making venture, but still, we all can't deny the fact that we do have many gamblers whom making money off gambling is their major goal, so, for such people, trying to recover what one have lost is not such a bad thing to do, it is what makes gambling even more fun and entertaining, that is, not allowing yourself to be beaten. But then, in the quest to recover what is lost, we must do it with all responsibility, and strategically in such a manner it doest lead into more loses out carelessness.
The thing is that loses happens and we need to try the best we can to avoid letting it get to us, to the point that it will put us under pressure to recover, and this is why we always advocate to only gamble with what you can afford to lose only, so if you are gambling with such mentality in place, you don't have any problem at all if and when the lises comes.
But just as you said, it is not a bad thing to try to recover from your loses, but in doing so there must be some level of procedures and total avoidance of pressure, Because that is the only way a gambler can truly escape the chain of losses when trying to recover from one.
