what we need to remember is that we are gamblers, don't be too greedy because greed will harm ourselves and that is not very good.
I would rule out such persons making a constant win throughout the year,otherwise this people would be on the increase,other gamblers would have done the same and since we are seeing the break even as the highest achievement for people who continuously gamble that means that being in profit constantly through gambling is impossible,even in games where skill is more relevant than luck,one dose of bad luck and all your wins are out of the way here also.
I think plan all you want but if you don't stick religiously to it then it won't have any real effect,we will be still struggling and losing in the long term against the casinos.
