I think one think you are very likely to learn, is that ten years from now that will still be true.
Not necessarily the "novice" part, although you'll still frequently feel like one. But the no where near being an expert will always be there.
With this stuff, we all learn, everyday. And if we don't then we're doing something wrong.
The expression in my signature picture "Really knowing is ........ Knowing you don't"
Is pretty much the fact of an IT career.
So get used to it and learn to embrace it. The actual benefit comes in the learning.
