I suppose that you can have too much of a good thing.
Like yourself I don't intend to go commercial... a bit to old now.
Flying is something I get into for a while then leave for another while.
Same with gliding...
Things are beginning to get a bit stale at the moment again, if I leave alone I'll miss it and then get into going on trips again.
I suppose I have active and inactive periods but it's always there.
