A fantastic post Paolo, you know what you want and i bet you get it too.
I am also thinking of leaving a stable career with excellent wage and working conditions, i even have a 6 hour a week gym component built into my contract lol. Although everytime i see an A320 or even a Dash - 8 leaving the airport i think i'm not going to die knowing i didn't give it my best shot.
With the miss' keen for some adventure i'm off to GA next year. Dreaming or not realising reality, i don't care. I'm not getting to 50 and its all to late.
