The strategy may not work well for you or is not enough to win but you should continue with patience. In fact, the efforts that we consider useless are not actually useless because we are gaining new experiences by losing in gambling. I think luck never loses in gambling.
I'll disagree and agree with you. Success comes only when you've the luck to hit the jackpot. It may demand you to applying multiple strategies before you can find that key since the compass of where the winning are spot aren't ever predictable. Sticking to one particular strategy might take you some tough time before the table turns round to your position.
Gambling is just as somehow like the raffle draws. Holding on to strategy one can also ruin the fun because it's like you're acting like a dump head who feels comfortable in loosing at all time and yet can't give try of other strategies to see if you can make difference on winning. Sometimes too the table turns quick around to you when stayed consistent. In all, there's nothing like winning strategy.
