It's pretty hard to have some personal time when you have your own family. However, it's still possible.
As an amateur astronomer, I still try to go out after all the kids slept, and then I will try to rush back home before they usually wake up. Of course, this could be really hard, but then it's still possible.
And there's some easier way. For example, when my daughter is having interest class, I will usually try to bring her there if I am on leave, and then before I picked her up, I can walk around and have some personal time, too. I have tried to do solar imaging outside, I have tried to take photographs, etc.
This time, my daughter is having a piano class at home, and then I took my camera outside to have a 30 minutes walk, here is what I got:-
It's not something special, but to me, it's good enough to have some personal time.
