A new musician is satisfied if he gets most of the notes on a song correct, but a more proficient musician is deeply troubled if he does not get almost all the notes, and an expert is desolate if he does not hit almost all the notes.
That’s a good analogy, but you didn’t take it far enough.
Any professional classical musician expects to hit almost all of the notes. “Hitting the notes” is no longer his goal. (In some cases this means that his goal now is to be paid enough to be able to eat fairly regularly and sleep indoors. But we’ll ignore that for the moment

) His musical goal now is to understand the piece of music and play the notes with the expression that makes each individual piece of music tell its best truth. For a very good musician, this may mean trying to understand the mind of the composer and trying to express the composer’s thoughts. For a genius, it means understanding the music without the “interference” of the composer–understanding the “soul” of the music and communicating that to others so they can understand as well.
As you grow in spiritual life you will begin to worry not as much about sins committed in deed, but even wrong motives for good acts–It’s not enough to do the right thing, you have to do it for the right reason (with the right expression). If you become a very good person indeed, you will really come to detest all sin because of the offense it is to God, because you have come to know God better and understand deep down why offending God is always wrong. If you become a great saint, you will come to a place where you have aligned your will to that of God to such an extent that you can play your own life as a piece of music–it will no longer be merely “Thy will be done” but “Thy will be my will.” (Note: Christ had no need to pray the latter sentence because it was always the case, but we are fallen, and we need to get to that place.) Pride does not happen in the last stage because attention is too focused on God.
Note: I do NOT know all of this by internal experience, but I’ve sometimes experienced the very beginnings of it myself and I have seen the later stages in a very few others.
So, yes it is OK to note that you have made progress. It would be silly to pretend you haven’t if you have–humility does not require you to lie to yourself. Looking at how far we all have to go should be a good aid to humility, however.
