It is much easier said than done, especially to those who has been highly dependent with the winnings gambling can give. I do agree with you that with optimism, a new perspective can be developed to turn away from gambling. However, sometimes it can really be hard for people as they don't have the courage to let go of gambling. Maybe if they have a new perspective and be open to actually stopping, then there's a chance that they could let it go but if they themselves are leaning more into it, then the chances are low. It takes more than optimism, but with the right attitude, things could easily be eased.
