Where's my Grit?

After reading the book "Grit" by Angela Duckworth, and scoring low on the questionnaire.. share where I lack grit and where I actually have it. Is it nature versus nuture? Both my parents pushed for us to just have good grades and go to college. Extra curricular activites, where grit can be made, wasn't a big interest of mine. I've tried plenty of activities to find my interests, however, everything I stuck to was to get out of somethings. For example, joining sports in high school to avoid have physical education classes or the time I became a "Stat" girl for the Boys basketball team to get out of 5th and 6th period during our away games. Is that grit? In this episode, you can hear my thoughts unravel as I figure this one out. Where's my grit?
