Tam:
1: Agreed, that point was for Derech, not you.
2: Agreed there are multiple definitions.
3: You talk about “Mesikus HaTorah” when I (and you) talk about Limud. First, who says you can’t have “Mesikus HaTorah” the same learning full time as learning full time with going to classes two nights a week (or online), second, I already said if you can’t learn because you are learning a parnassah, then don’t learn the parnassah.
I think we agree.
