I can attest. After 7 years of practising guitar, the gap between my ability and my taste is even greater compared to when I started.

Actually I can say the same thing for programming, I can build most software I would think of building when I started 20 years ago, but there is still a large gap between what I can build but what I discovered later and now would like to be able to build (I'd need to learn lots of maths in addition to other things).
