I'm in a similar position to you (and location by the looks of it!). I'm about 20 hours in to my PPL training now and some months are harder to justify financially than others and I expect that will be true once I've got my licence. In reality sooner or later life will probably get in the way and I'l stop flying for some time, maybe forever. I love learning this, I'm enjoying it for its own sake and that, to me, is worth every penny.
