I too have an Addictive Personality.
I saw on MSN a girl addicted to eating toilet paper! I want my 15 minutes of fame too; maybe if I tell MSN I'm addicted to alcohol? Nah, too many millions of us.
Seriously though, jamdls has the right idea here. Make it healthy (or at least benign) and keep it balanced to where it doesn't adversly affect the rest of your life. Balance is the key. People who find something they don't get tired of are truly blessed. The rest of us jump around and mix it up.
