Confidence is only limited to the adrenaline produced from positive thinking, you never know the end result before something starts. Borrowing money to gamble or invest has risks that can cause psychological problems when you have difficulty paying it, especially if you borrow money from moneylenders that must be paid on time plus interest. It is necessary to reconsider all the risks associated with using borrowed money to gamble or invest. If the amount is small, it may not have a big impact, but if the amount is large, it will have negative effects that have never been imagined before.
