I feel doubts and affairs can create a problem in gambling as they can lead to a lack of focus and decision-making ability. Gambling requires a clear head and rational decision-making skills, and if doubts or affairs are on a person's mind, it can affect their ability to make logical and calculated bets. Doubts and affairs can also lead to emotional reactions and impulsive behaviors, which can result in compulsive gambling and financial losses. It is important to address any personal issues and concerns before engaging in gambling to minimize the risk of problems.
