But in order to learn you also have to know what to learn! Resulting in you have to know before learning.
True, but think before your logic of what you wanted to learn. I would have imagined that you had to research, stumble or be influenced across what it was that you wanted to learn for a specific subject. So as the basic first step, not knowing and reaching the desire to study a certain task/trait/etc would be the first step to learning. In my crossings of the definition of 'noob', many people have different views. I don't believe everyone is 'new' but rather have different expertise. A mechanic may not be a good electrician just like a programmer may not understand the full design of networking. I think the key is to be a humble person since there is always room for improvement, to help others which in turn may help you.
