I second all of the comments above regarding gliding and 3-axis micro-lighting. I fly many different GA types and am studying my ATPL Groundschool while working full time but I still fly Eurostars when able even though the hours count for nothing on my licence - they're just so much fun and so more capable VFR than a Cessna or whatever most people learn on these days.except perhaps the new Tecnam my club has just taken delivery of!
Also, ask you instructor to introduce you to people he thinks you wouldn't learn bad habits from if you went flying with. Maybe they'll let you do the RT and nav as well as being good for the to talk you through what they're doing.
