Words are funny things, they have different meanings, and in the case of words with such broad opportunity it is my responsibility to clarify myself. That's why philosophy books always start out defining terms.
I put "purpose" and "calling" (and "mission") into a category of fixed, one-dimensional, outcomes. "My calling is thing X, that is all I do."
Same thing with "meaning". It is too big to be meaningful, ironically.
For me, what gives life value is experiencing peace of mind and detachment from suffering: it is what it is, along with novelty so that it doesn't get boring.
There is no "meaining" in there, no "purpose", no "calling", in this world-view.
I'm trying to steer OP away from a certain fixity, which in my experience (both in myself and in observing others, and in reading) only leads to more anxiety.
