"Meandering" is often only in the eyes of the beholder. If one person "beholds meandering" then there's a really good chance that the person in question has sensed that the other feels free to judge. As a result, the one with some talent of some kind (or many talents, for that matter) may well know exactly what his priorities (maybe even plans) are at a given time, maybe be keeping his interests/plans to himself until he has something more concrete to share.
I'm not in the business of judging other people. Neither am I in the business of assuming I know that because I don't see them doing something that can't possibly be doing anything. And, neither do I offer unsolicited advice about what someone else should do unless/until the person asked me.
Someone who APPEARS to someone else to be "meandering" may be, say, young and trapped on a modest income because he has the good sense not to want to be homeless AND to prefer to be independent (even if that may mean, say, needing room-mates for a time). If someone feeling tempted to judge would ask the person AND listen to him then it often becomes clear that it's not a case of "aimless meandering"".
I refuse to judge a situation that I can't possibly understand (unless I were a mind-reader, which no one is, of course). And, I refuse to be such a narcissist that I would assume a) just because I don't see someone's aims, efforts, plans in concrete form, and b) the because I don't/can't see what's in the person's mind and/or personal life (when I'm not around) that "must mean" there's "nothing" in the person's mind/plans.
