DH & I overheard our neighbor tell his teenage son the he doesn't care whether the boy gets C's or D's in school... "grades aren't that important". DH & I near fainted!
We're not C's & D's kind of people... we're the type of people that will ask our daughters why the didn't get ALL A's when they bring home report cards with one B on it.

It's one thing to struggle in a subject and to continue to struggle in it as long as you recognize your short-comings and actively seek out help from either us or a tutor. It's another thing entirely too be lazy.
Have our high GPAs and Honors diplomas and fancy cords at graduation gotten us ahead of an average person? I doubt it. Our teeny tiny house and teeny tiny budget are saying "no. Definitely not." But we're not the type of people to accept mediocrity, especially when rooted in laziness. We place a very, very high value on education.
