After I got my PPL, my next flight was with a friend. We went to the Isle of Wight, which neither of us has been to before. Then I went with my brother to all the houses we had lived in etc... Then I got checked out in something bigger and when I got to about 40 hours total (I got my PPL at 19 hours via a "Silver C" conversion - are they still possible?) started towing at my gliding club. After 30 hours towing, was then tailwheel trained (another tug). Had I not got a commercial licence I think I would have bought a share in an open biplane (long or short wings).
I'm not suggesting that you don't lack imagination, but I never really understood what you do with an aircraft untill I spoke with people who I met socially at gliding and aeroclubs. For the record I was a member at West London Aero Club (White Waltham - I hope it hasn't changed too much) and LGC at Dunstable. Therefore, may I suggest that you join an aero club with a social scene.
Best of Luck
