I got my PPL in 2002, and am just coming up for my 2 year renewal. Done about 100 hours now, but what with working and the weather find it very difficult to fly as much as I would like.
Started a night rating twice, both times ran out of night due to wx cancellations, and also started but not finished an IMC.
I do find that I enjoy flying with another pilot most of all - it's much harder on your own, and can get a bit boring.
