Hi Manthy, there is no such thing as an addictive personality. Everyone is capable of addiction to something, it doesn't have to be "bad" to be an addiction. Some people are born with less "good chemicals" than others and that may predispose them to certain substance abuse, but not everyone is addicted to drugs or alcohol. Some people are addicted to foods, playing the guitar, emails or exercise. Do you think you would become addicted to tats, or just obsessed with them? Obsessive personalities become focused on one thing for long periods of time, but it's only an
"addiction" if it causes harm in some way. You know yourself well, and you should go with your decisions.
