Are you usually an anxious person? I wonder if being anxious makes you more susceptible to being addicted to gambling or no?
If you are always worrying, would you not be able to take risks as confidently as others? Won't you just stay in your safe zone and miss out on opportunities that could have given you bigger wins? Or maybe some people tend to forget about their anxiety from gambling because their mind gets so numb playing?
Has gambling treated your anxiety or has it made it worse?
It will make you out of focus and everything you do is unsure since you are not in right mind placing your bets. So provably in that situation you have huge chance to lose more money.
So if they really want to win better focus and don't entertain any possible negative things. They should stick on what they believe right for them, since always worrying will not bring any good result on the games they played.
Better for people have those feeling is to quit and just comeback when they have huge confident that they are doing the right thing then have good chance to win.
