As a gambler it's very important to limit yourself on how much you are willing to lose and set a limit on how much you will stop if you win. And to back up your hobby you should have a decent way of earning like investing. You need to have it first before getting into gambling but just treat it as a hobby.
Well there's no denial that there are people that is choosing to gamble and makes it as their hobby. But I'm saying that before you have an addiction make sure that you are getting the money you gamble from your own pocket or from your own source of income or any investments that you have.
