How does GLOG Conviction work?

In The GLOG V1, it says, "You gain a point of Conviction whenever you follow one of your Convictions. You cannot have more than 1 point of Conviction at a time. You only gain a point of Conviction when following your conviction gets you into trouble." Does that mean you have either 1 point of Conviction or none? There's not accumulation, just 1 or 0? I don't get how that's to be used. Thanks for any insights.
