I head a story said over by a Rov on Friday night in between Minchah and Maariv.
The Rivnitzer (a known baal mofes) was known to daven at more peculiar times in line with chesboynoys, but would obviously not daven without a minyan.
He once called a bunch of jews together that hadn't davened with a a minyan yet (if I recall correctly, it was for maariv which can be davened at more peculiar times like late at night). While ushering them in to a room to daven, he stopped one of the jews in his tracks and said that he couldn't be part of the minyan because he had davened.
The person was asked, "Why did you join the minyan if you knew you had davened?" To which he replied, "I never knew my tefilos registered in Shomayim!
Sometimes we don't feel the change we make. We aren't meant to. This world is for הסתר (albeit different degrees and forms). Ok, maybe I couldn't feel the kedusha. Still, great job

.
I struggle with this a lot of not feeling our affects, inspiration & results. It's not what we should be striving for, I don't think.
I'm not saying we should go purely based off of intellectual understanding and resolve. We should for sure feel meaning. But if we don't doesn't mean we are failing.
I'm not sure where the middle ground is. Thoughts and ideas are welcomed.
I'm sure the chevra here has a lot to say about this. Looking forward
