Flying an aircraft requires responsibility and decision making. I take it from your answer you didn't have to take full responsibility in difficult circumstances when you had little experience. I have had to do so - and I can tell you it is about a lot more than being able to fly the aircraft!
FFF has addressed your points with some very valid challenges.
Might I ask how you got into a 320? Integrated course and straight to jet / turboprop?
