Oh heck yes!
It takes time and patience and perseverance and the application to actually learn it. And none of that happens overnight (at least not unless you are outrageously talented)
Over the last three years I can remember several milestones that made things both better and worse! I can remember learning to use a lightmeter properly (huge plus) and I can remember learning how to work studio flashes and off camera speedlights (huge plus) But then I can remember getting my hands on my 1Ds and feeling like I had lost a year. The results looked like it too! I had to go back to a routine of checking ISO, what metering mode am I in again? white balance? oh good grief, it was painful. Now I've actually got the hang of the dratted thing I can concentrate on what I should be looking at. Light, positioning, interaction....
Any time you try to work on one particular aspect of your photography, this will happen. Metering, composition, lighting. It will all be pants until you get to the point you actually make progress.
So don't let it worry you, it's natural and it will get better.
