No. Well at least for me.
The gambling is something that has to do with countless things... let's start there, then, you don't start betting the moment you literally do it, that is the first mistake.
Since, first of all and regardless of religion , beliefs, being a good son, husband, father, and in general fulfilling your responsibilities is your first big bet.
Consequently, the first bet you make is with yourself, so, if you don't know yourself, or you have doubts, the other best thing you can do is pay for a consultation with a person who does coaching, or a psychologist, who will evaluate your mental abilities to understand if you can enjoy gambling without addictions.
Now, even if you feel good with the previous two, your results are never measured by a single value (+.-), it is the long term.
Say no more brother, what you wrote says it all, and this is why I like saying that gambling isn't for everyone, even though everyone can be a gambler, many people will be messed up in the end.
If one can't even trust himself how can they handle gambling? For such people gambling will become a psychological suffering, they won't be able to keep up with all the necessary disciplinarian acts of a responsible gambler.
So the first check must be awareness, what are you all about, can you really handle gambling and not go out of your boundaries? Etc, these are personal challenges before one decides to start gambling.
