When I read the following sentence out loud to myself, it seems to me that there should be a brief pause before and after the word 'still,' based on how it is being used in the sentence. However, I am unsure as to how commas should be placed around this word (if at all) to create the correct effect:
"What initially motivated me to explore the field of robotics was the realization of the, still, countless opportunities for robots to play a role in people's lives, and have a significant positive impact in doing so."
Is my comma usage correct?
