Is it possible for an INTJ to not have a plan/goal. Perhaps this person had a plan once, but it failed... and now he hasn't got a plan. He does have enough drive to say I need to move forward, but (with limited opportunities) no clear idea which direction "forward" is, or if there is even a way forward at this point at all.
Though when a goal is found that this person can get motivated about, he puts all his energy and effort into it. at this point, it can just be difficult to get motivated about much. (though running his own business was never something that interested and motivated him).
