Everyone has their own ideas and perspective of gambling, some believe that they can make money from it others just use it as a way to pass time expecting nothing from it... just like you said taking it fast or slow doesn't really matter because you can still lose using any of these systems..what is more important is how you manage the risks you take.. gambling gradually or increasing your stake is your choice but it can only reduce your losses when you plan out your bankroll.
Most of the people that believed that they can make money from gambling are not yet rich, they are still poor, left in the same stage that they were for years now, is that not self deceit? Best way to go about gambling is to not have a very high hope about making money with it because such hopes has made some people poorer and frustrated some people, while some people also lost their life for it. Some people chase after gambling, leaving to do what's so important that can fetch them money consistently.
