I mean seriously. How can my teacher expect me to think back on ever assignment I've done and reflect on why it's important to my future?
The vast majority of things I have done that are important or relevant to my future were
after I graduated from high school, and those that were before, were not school assignments. Most of my high school and prior work was busywork, and it was a very poor preparation for the real world (other than getting the credentials, which was worthwhile). College was much better. So I can sympathize with having trouble with such an assignment.
But I do still have
all my assignments back to 6th grade (maybe before also, though not immediately accessible).
