In gambling when you play to recover I feel that is your biggest mistake because it is not easy to win and not always you have that luck which might help you. So better to just gamble for entertainment and have a great time rather than getting into this and people who cannot control will become addicted which will be again a bigger problem.
That's inevitable when a gambler plays to recover. Its a big mistake for everybody but you'll never understand on how they badly feel to recover those losses that they've made. And to tell that to everybody it can't help and no one would stay with that situation for a very long time, you'll always think of those losses until you gain more as you gamble again.
