Despite your claim of some noobies picking up romhacking right away, It is the fact that having previous programming/coding knowledge of any kind seems to greatly assist the speed of the romhacking learning curve, and I promise the vast majority of rom hackers this is the case. Without this, it is going to be very time-consuming indeed learning the ins and outs. I myself stick to what interests me enough to learn it (event and music) which requires no assembly coding but is still difficult to pick up right away. Learning assembly or any coding language isn't going to be quick, so hang in there buddy! after a certain point I think with learning anything a breakthrough moment of clarity happens where things start to click a lot more. It just takes us all different amount of time to reach this pinnacle as we are all different in terms of brain chemistry - what might take one person to learn something a year could take another a month. That's just the way it is, gotta just stick with it and strive for understanding and improvement which it sounds like you're making 
We are born, live, die and then do the same thing over again.
