Addiction is the state of not having any control over your habits. Controlling what you already have no control over as a gambler is very difficult. What the gamblers should be talking about at the moment is how to heal completely from their addiction. In most cases, quitting gambling for a while to pursue other real-life activities like a real job, bonding with friends and family, and engaging in hobbies is the only solution.
For gamblers who are not yet addicted, they can help themselves by controlling how they gamble and how much time and money they spend on gambling. It is easier to do this now than to wait until everything gets out of control.
