Basically I think the difference is, if hanging back and observing all the time, and not feeling competent enough, trips you up, then you're more likely a 5. If it's anticipating worst case scenarios and trying to prepare for them that trips you up, then you're a 6. 5 doesn't feel the drive to engage as much externally. 6 feels like they have to engage externally because they have to prepare. 5 does more watching in the present and theorizing. 6 does more future thinking.
