This is when my second shift starts. I pick up the kid's area, clean the kitchen, dishes, laundry, and whatever other stuff is left over. After that I do another 2 to 4 hours of work depending on when things are due, late to the bus, early to leave because of family stuff. In bed somewhere between 1am and 4am.
I keep track of my life in todo lists. Got a notebook and a pen within arm's reach at any given time. Zero Inbox/Bullet Journal/GTD my entire life, work and personal. I also naturally do sort of a pomodoro technique with everything. Breaking it down into smaller parts so I can cover as much space as possible. Cleaning the kitchen turns into two separate tasks (dishes, and cleanup) which I then inject 10 minutes with the wife or kid in between. It probably adds more time to my overall day, but I can't push their schedules later and I need to get work done so I can't push my duties to later either.
The other "trick" is I've never needed a lot of sleep so I can do stuff later at night once everyone is in bed. Sleep on the bus, or whenever I have a free moment.
My previous job was within biking distance so that was my health management. Now I have to ride the commuter bus so I'll have to figure something out once the 2nd kid comes.
