Someday your children may have to fill out forms that ask for their parents’ levels of education. It may embarrass them to write that momma was a high school dropout.
Never mind, how potential machatunim might view this when considering your child in a shidduch. I would not think a family valued education highly if a 21st century parent didn’t at least have a high school diploma.
Yes, this is judgmental, but I’m being a realist.
You will not regret finishing your work and getting a diploma.
