not only eagerness to win but also the willingness to make fun . yes most of us enjoy gambling in order to past the time but if they hooked in the game too much they didnt even realize that they are already addicted on playing . every game do also have a different set of odds . lottery has a higher odds while most online gambling do have a lower odds which we can easily beat them but then again addiction will suddenly strike to us .
When I gamble I always fall for the odds even though I know that winning this odd has less chance. Here is another problem I face. When I lose I double or triple (even more) the bet and if I lose that then I do the same.
So I found both the odds and chasing is the cause of gambling addiction.
Well actually the odds are important. If you think you have 10% chance to win the wager, but the odds will give you a return of 12 times your initial stake, then it is worth it. Too many people forget about this, but this is the right way to consider a wager, in my opinion.
When I lose I double or triple (even more) the bet and if I lose that then I do the same.
This, is of course not good

martingale, can be good to win money short term but dangerous if you use this strategy too many times.
