I can be considered a newbie in gambling and it wasn't good for me. I lost money when playing, so I lost some of the will to continue playing (and the money too). I didn't lose much, because I don't have much, but now I need to continue getting my pennies and while I work on it I can think if I will continue with this gambling thing or not.
It is not only you lost money in gambling just because newbie but any other experts also lost money in gambling because gambling is required luck to money, not the experience. So if you have decided not to gamble any more then that is a good decision and you can save lot of money by stopping gambling.
