If having a positive mindset can be the sure way to win in a bet, I am sure we won't have the case of losing consistently in gambling because it is in every gambler's belief that they gonna win in their bet. The bet they're gonna win is what we gamblers can't ascertain, but we have it in our mind that one day we will win. I think that's what keeps our mind at rest to keep trying our luck on gambling every time until the day our luck pays off for a win in gambling
If a strong mindset were one of the main aids to winning at gambling, then people would not lose a single bet. Great people would develop a strong mindset with the advice of great psychologists. A positive mindset may be important in all other areas, but a positive mindset does not play that much of a role in winning gambling bets. This is just a misconception among people because how will your state of mind or mindset affect a Slot, Dice, Poker, Sportsbetting bet?
However, gambling with a positive mindset can play a very important role in controlling yourself later.
