1Knowing something calmly and feeling it are two separate achievements, and the second takes longer. If you can say the reasonable thing but it does not touch how you feel, you are partway, not failing.
The gap does not close by arguing with yourself harder. It closes by living it: doing the practice in real situations, in your body, while the feeling is actually present. More explanation at the kitchen table will not get you there.
Islamic evidence
We shall show you the easy way (Quran 87:8). The route from knowing to feeling gets easier by being walked, not by being studied.
“We shall show you the easy way”
Qur'an 87:8
Psychological evidence
A randomised trial in panic disorder with agoraphobia compared exposure carried out with the therapist there in the real situation against exposure simply prescribed for the patient to do alone. The guided version produced more pervasive and longer lasting effects. That is one anxiety trial rather than a general law, but it favours doing the thing in the real setting over discussing it.

Why it works. Feelings shift with the experience of doing something, not with agreeing to it.
