Not for everyone. Not all people are subject to gambling addiction; why should a person who is not concerned with such a problem stop playing if he needs to at some time? This applies to any activity that we like. If alcohol does not cause problems, there is no need to forbid yourself from it. If games are part of some entertainment, on par with visiting a restaurant or bar, and are not regular, there are no problems. Human psychology is built on attachments, but a sense of proportion is always in everything necessary; if it is not there, then you can get a bad addiction even to food. Hence the question: is it worth stopping eating if you do not know how to cope with your passions?
