The more I learn about flying the less I feel that I actually know. EGKB, I'm sure you're going to feel the same way in the future. At the moment it's easy to feel that you know a lot because you've played around on a simulator, and had a go at the basics in the air, but as you get experience and particularly when things start to go wrong in the air, you're going to start asking questions of yourself. You'll only discover you're own limitations through experience so while you have less than an abundance of experience you need to rely on your instructor to recognise those limitations for you and to spoon feed you at a pace that you can keep up with, and they will likely do that with tried and tested techniques. You shouldn't feel the need to critisice those techniques at such an early stage in your training. Enjoy yourself and don't over-reach. The fundamentals are important and believe me, there will be plenty of times that you struggle to stay straight and level in the future!
