Someone once told the Kotzker Rebbe that he was struggling to find meaning in his prayers. He hoped for some sagely advice from the master. Instead the Kotzker simply said; "Don't worry about it."
The nature of prayer is such that if one prayed with meaning only once, all subsequent prayers, even the imperfect ones, are drawn to it and get get elevated through it. (Emes Ve Emunah, Hakdamah)
This is a typical response of the Kotzker: short, radical, realistic and deep.
