Artificial intelligent assistant

the use and the meaning of the verb 実感する in the given example I would like to ask for help with translating the following sentence: I understand parts of it for example But my problem is putting them together in translation of the sentence above. Also, I found out that means "have a feeling", "my actual feeling" is or "to realize", but I can't make it out which one is the right one here. So basically, I have problem with the use of the verb , furthermore with the translation of the whole sentence.

Something like

>
> Today I experienced the sad line "the fact of not having practised doesn't lie" for myself.

If you gave some context there might be a more fitting translation.
