All things can become addictive, if you enjoy it so much, the secret is does it do you or others around you any pain or damage, If you can answer No! then what is the harm in it, I promised my Wife I would not deposit any cash on any
poker site, and I have kept that promise for over 20 years now.
I don't need to deposit, because I only play for fun and play the Free-rolls until I make enough money to buy-in to games. So any money I gamble with, is money I never had, so I can never lose.
Poker is a game and should be enjoyed as such, but when you start to overstep yourself and play beyond what you can afford to lose, then it can become a problem, not only for yourself, but your Friends and Family, Just like Drugs and Alcohol, if you need that fix, then nothing will get in your way to get it.
I learned that lesson many years ago before I decided to settle down and get married, I used to gamble a lot, and sometimes lost my week's wages on Horse racing and Dogs, being single it was fine, as I would not hurt anyone but myself, but after I met my girlfriend and decided I wanted to get married to her, I gave myself one choice, was it going to be her or the
gambling, as the two were incompatible. I bet on her and it was the biggest win of my life, We are still together 45 years later, and although I may have a flutter now and again on a day out, or for a bit of fun, I will never lose an entire week's wage on any form of Gambling!
Keep it simple, Keep it fun, and always remember--
When the fun Stops, STOP!
