To preface, I don't view it this way at all. I'm in full time education right now, with the intention of being a SAHM in the future and (probably) home educating my kids.
I don't feel any education is necessarily "wasted" as you still gain something from it, but there's definitely a niggling feeling in the back of my mind that I'm doing it for very different reasons than my peer group.
Interested in hearing opinions (though please let's try and keep it respectful to both SAHMs and WMs). Thank you!
