Yes gambling no matter the strategy or how clever a gambler may be putting first to accept losses is a paramount thing because losses is inevitable, the only thing I see in having a strategy as many gamblers know what work best for them is that those strategies may eliminate some losses if one has more knowledge on the game he want to gamble on but but percentage of wining is usually lower than losses.
Strategy of stoping once one begin to experience losses beyond expectations is the best option because since gambling is a game if luck if the time has already been scheduled to give you loss continuing in such game may rein you down that is why gambler who is clever and smart control their losses in a little manner but not completely in loss control management.
The thing for an strategy is to make sure you have more upside than downside. As you say loses are innevitable and always linked to the fact that gambling has an chance or stochastic component - if not is not gambling - that is difficult to predict, so the key for an strategy is to take that into account and ensure that the big numbers and the long term present a favourable predicted result for the user.
some sort of holy grail. Then sooner or later you would be finding yourself that huge problem on the moment that you would really be able to spend up tons of money because of uncontrolled gambling activity.
Strategy could give out that kind of thrill though, it is really just that it would really be best that you should really know on what you are dealing on with.
