There are many things gamblers have in common as long as gambling is concern. One of them is hope or should I say optimism which is the driving force that keeps you wanting to continue despite setbacks I the form of losses. Without this driving force, a lot of people will not be gambling since gambling involves a lot of risk taking. Despite that gambling can be fun, there is always the risk factor irrespective of how much you gamble with.
Being optimistic when we gamble is normal. We think that it's our lucky day and that keeps us gambling even if we're in losses.
The risk would be just fine and we as gamblers can take that because what is on our mind is we'll get back to it the next day.
So, the fun is actually on how we recover and you'd see the same stories of losing and drawing back to gambling despite being in a losing streak.
