if you cant answer that question yourself in a proper way, then maybe you didnt really want to be a pilot appart from the money (LOL) and prestige.
you cant take somebody else reasoning and put it as yours. everybody will look trought it.
but your answers are already good dilan, so dont worry! the key is just to let them feel your passion about flying and not answering in a generic way. they need to see your eyes sparkling when talking about this topic.
