The usual answers as above, plus I love the sense of achievement learning to fly has given me.
At several points during my training, I couldn't envisage actually ever getting to the point of gaining my licence. Yet here I am, 18 months from starting my lessons, with my very own brown wallet, as many hours P1 as dual, a night rating and I've now started my IMC training.
It's been a journey of self-discovery as much as learning to fly. Long may it continue...
