If you want to see a person full of hope and belief, then gamblers are the perfect example. The hope of winning and the belief to win is found in gambling. Even if you tell them that gambling is risky and the result may come out differently (not in his favor), they refuses to accept it and have 100% belief that they will win at any cost.
No matter what you will tell a addicted gambler about the risk associated with gambling, they will never listen to you, if you tell them about how risky gambling is, they will end up telling you that everything in this life is risk, so if you are not ready to take the risk you can never be successful. They are having confidence that if they keep on gambling (taking risk) there will be a time that they will be successful, so that’s why no matter how risky you tell them about gambling, they won’t listen to you.
We are not talking about the result which comes later on, once they gamble. They may lose too but the passion and belief of winning among the gamblers can't be seen anywhere else.
Addicted gamblers don’t care about spending everything they are having on gambling, then after losing some might end up regretting, but when they are having money again, they will still end up going back to gambling, and some might not even regret that they lose. The way gambling is risky, nobody should always have assurance that he/she is going to win, no matter how sure you are on the games you played your bet on, slight mistake can happen and you will lose everything, when gambling we shouldn’t be too confident that we are going to win, because if you lose, the shock can cause some health challenges.
