I would pay off the mortgages on our home, as well as my mom-in-law, dad-in-law, sister-in-law, brother-in-law, and hubby's 2 step-siblings. My mom is in an independent living home, I am not sure whether I would move her to a nicer place or buy her a condo and a live-in caregiver.
Admittedly, I would not continue to do home childcare. But that's because I wouldn't plan to "work" at all!! :P I would travel, probably for a couple years straight, to cross a bunch off the "list". I would have to bring a tutor for the kiddos. Then we would settle down, and my kids could go to a local private school that I've been eyeing up. I could do all the charity and benefit work that my heart desired, and be a 100% full time mommy. My hubby could do.... whatever he wanted, hahaha.
Hmmmm. Had no idea how clearly I could envision it, until I started typing it out!!
