Paraphrase the sentence, “In my experience as both a learner and later a language practitioner, one has to have a drive that will obstinately motivate one to succeed against all odds.”

"In my experience as a learner and later a language practitioner, one has to have a drive that will obstinately motivate one to succeed against all odds."

Is this right? Thank you.

What in the world do these mean?

"a language practitioner"

"one has to have a drive"

"that will obstinately motivate one"

And this is a downright cliché:
"to succeed against all odds"

Simplify, simplify, simplify ... and then re-post when you have done so.

"In my experience as a learner and later a language practitioner, one has to have a drive that will obstinately motivate one to succeed against all odds."

Yes, your paraphrase is correct. It captures the meaning of the original sentence while using different words and sentence structure. Well done!
