What is grit?

I already knew the answer. #thatswhathesaid

So many times throughout my academic career it felt as if everyone else [those I deemed to be successful/fulfilled] were miles ahead of me. I was still trying to find where the track was. I can recall experiencing overwhelming anxiety whistle trying to figure out how to apply. I was on my own. My high school guidane counselor didn’t offer or did he seem interested in talking about it with me. Both my parents didn’t know what steps I might need to take. All my older brothers had never even contemplated going to college.
