I think yes. Being positive gives us more space to think and we can come up with a new idea, new strategy and we can also control our mind and body. If we can not control our body, we can become too greedy and then, in the result, we will lose our money in gambling
You don't have to be greedy to lose money. Gambling is game created for you to lose money, no matter greedy, not greedy and no matter how positive or negative you are.
I don't see how controlling your body can help you in gambling. Do you?
I don't see how controlling your body will affect the outcome either , nor what strong feelings you get whenever placing a bet will does .
It's all about luck and the outcome can infinitely random no matter what conditions your metabolism is ..
You should rather control your gambling practices and know where did you screw up and where were you good whenever following some strategy , and on top of all you must control your spending since frustration can make you spend even more in hopeless attempts to get your money back ..
Positive thinking will certainly not affect the game circumstances , house's edge or what could happen at any given time during the whole process .. so this being positive thing won't make you any money , being smart will tho and that's my advice for any gambler : whether you are willing to take risks or not , whether you are greedy or not , the more you play it smart the more benefit you'll get
