I gamble just for fun and passing the time. I believe that everyone should play for the enjoyment and not with the intentions or greed to win big amount; if you failed then you will be disappointed and might play more and loose more money if you look for covering the previous loss.
I do not gamble that much anyway. Just that most times, when I have a few free cash lying around, I always want to have some fun and some little bit of rush at the same time. Gambling has always been fun most especially poker. Once I am done with what I came in with, then I am done for that gambling session which usually could just be once in 2 weeks and if I dash away with some wins too, then all the same. Just the fun and I purposely set my mind to that so I don't get messed up. lol
