How do some parents do it all?

I've got it pretty good. This I know. Things have changed a little bit with Athena starting school and me dipping my toes back into real estate, but a typical 24 hour period for me goes a little something like this now:

After cuddling, kissing, nursing, and sleeping with my favorite 2-year-old, we get up and at 'em at 7:50am. We then join the sweetest 5-year-old in the world on the couch for more cuddling and some cartoons. I make the ladies breakfast, get them dressed, and take Miss Athena to kindergarten at 8:50am. After drop-off, Zofia and I take care of any household or school related errands and head home. I do some housework, maybe do some social media work, and take care of any real estate business I have going on. Zofia and I cuddle some more, have lunch, nap, then pick Athena up at 3:10pm. We do homework, chat, start dinner and then welcome home dad. After some family time, it's back in bed with Zofia to start the cycle over again.

Of course I get overwhelmed sometimes. Working at home can be a challenge, housework piles up, I've got duties to take care of for the PTA, and I never get a break for just me (unless you count grocery shopping, and until they start serving booze, I don't), but for the most part I've got it easier than someone that works full time.

What about when things change? What about when I have to get TWO kids to school and start working for real? Like how do you get one kid to elementary school on time, get the other one to junior high on time, and THEN make it to a job on time? How do people do this? When the time comes will I get one of those necklaces that Hermione has in Harry Potter to be three places at once? Is that how parents do it? Honestly, it's the only way I can think of.

Are you someone that does it all? How does it work exactly?
