Your opinion about where you lie on the spectrum of capability has everything to do with your own perspective-building and very little to do with "reality", whatever that is. You're comparing where you are with where you can imagine being, and both of those valuations are fraught with error. One of the harsh realities of acquiring skill and sophistication is that those enable a vision of where you <could> be, which is inherently frustrating.

Perhaps the real problem is finding a sense of satisfaction in your work. The algorithm for acquiring that is fairly straightforward: work your edges, i.e., focus on tasks that challenge your current capabilities, but not too much.
