I like your answer that we have to protect ourselves and avoid spending a lot and to have more losses. Because that's how it starts for most of the gamblers that have lost a lot and no longer can control themselves.
While they are very ambitious, there is nothing wrong being like that but we know our limits and we know where to set our feet and accept that we can only move a little by little in hitting our goals.
By protecting ourselves into not falling into many big losses while gambling also helps to maintain our long time stay in the game. Carelessly betting and not putting down some risk factor to abide by just makes you see gambling in a different form and could make you leave the gambling space sooner. It is clear that participating in gambling could make a gambler to be very ambitious, but trailing with care and applying risk management will make you not to be an addict which can lead to more and more loss and eventually exit from the space after broken down from it. Betting little by little will enable you hit the goal with time.
