In general I have seen that many players sometimes have a very bad time when they lose , in fact they start to die , but my humble advice is that Before playing, put the money you are willing to lose , no matter how little it is, it is intelligent to make that first plan and if you do what you should do is enjoy it, do not keep anything for yourself , exploit your emotions and if you lose you just have to accept that loss and if you win, do not hesitate to withdraw your Profits.
Your advice is indeed a nice one, I would like to emphasis a little on this aspect of putting
what we can afford because that's where the problem is, because some guys can decide to gamble with only what they can afford to lose but at some point they start gambling beyond their budget and maybe when the outcome didn't work as expected they start finding it hard to let go. Surely is good to accept lose instead of fighting back, because when we fight back it will result having more losing experience, so anyone who really understand what gambling is all about will never think of chasing after loses because they know the disadvantage of chasing after loses.
