Yes, its true. A strategy is just a way to win but still there are risks in those strategy. It doesn't work all the time. That is where you'll need discipline. If you think you're strategy didn't work and you keep on losing after using that strategy, why don't you limit yourself with your bets or if you're disciplined enough, stop playing for that day and wait for other day. In that way, you'll stop yourself from losing and losing.
