Very true indeed. To an extent, our individuality plays a big role in how we handle the 'play for fun' narrative. If i should use myself as an example, i get easily excited but not so easily discouraged. I find in most cases, the means if i win a bet, i'm likely to go even bigger (dangerous i know) whereas, if i lose, there is that feeling of 'i'll win the next one', and then it just goes on and on like you say.
Even though i know 'walking away' is a very important aspect in gambling, i feel it is perhaps the most difficult one.
I really think that is very risky but I don’t know how long you been doing this and how much it has worked for you, but left for me, when I win am just grateful for that day and if I lose, I do not even make attempt to recover, I let it go and this has helped me greatly. I think it’s better to do this so that you will not have record of loses on gambling.
