The problem for me and others of my ilk, is saying the same thing 3 times a day in a group minyan doesn't really bring connection, though it may bring relationship. for a bit as i stopped going to minyan, i tried davening alone in the beis medresh, and that worked for maybe a weak, but then i just couldnt shlep myself out to daven alone at shul when i could daven at home. and then i started cutting down on all the words.
Is it possible that if you would spend more time on iyun tefilla and truly understanding purpose of tefilla, the limud from sources like mabit, rambam, etc. (As if it was a sugya), you'd find more meaning in tefilla as established by the chachomim?
I am talking from a bit of experience.
When I was a fairly young bochur, I didn't have a taam for tefilla. I understood the words mostly, but didn't understand the point. Then I spent time, on advice of my mashgiach in my yeshiva, on learning some of the more hashkafadik sources. It changed tefilla for me.
And i sporadically refresh myself or learn new things on the tipic
Doesn't mean that 8/10 times, or more, I don't run through it. But it does make it more important for me. And it does allow me to try, at least sometimes, to daven with some level of kavanna.
I feel that it's quite important to keep on learning how to do mitzvos properly.
