I don't have a PPL, and yes I am completely jealous of people that can fly. (Just bought house can't afford to yet). But I do get to fly with club members and the flying school whenever I can. This gives me a better understanding of what is going on up there until such time that I can afford to pay for lessons.
Likewise, the club send all new students up to the tower for a visit , so that they can see what we do.
From my point of view (ATCO) yes I can get frustrated by new (and old) pilots, but when I was reletively new up here, I know that pilots were frustrated by some of my learning gaffs.
Swings and Roundabouts. Just so long as its safe!!!!!!
But I think that just simply getting to know your local flying school and nabbing the odd flight and pilots visiting ATC is a great help.
