A process, a pattern or how I operate in stages

I don't know how to balance my time - I find that I'm holed up in my garage, focused on making beads for a good part of my day- but at the same time I don't feel like I get enough time where I'm actually sitting and making beads. I also can't sit longer then a couple of hours, which is probably a healthy habit but I do envy those that sit for 6-8 hrs at a time- does that include bathroom breaks? Lunch?
(This is after I get the kids off to school) Usually I start my morning ritual with taking out yesterdays beads from the kiln and soaking those. Then starts the process of turning on the concentrator, starting the kiln again, turning on the propane and setting the pressure and then back into the house for coffee and breakfast. By this time it's 10am and I start to feel a twinge of panic; I only have a few more hours before the kids are home from school. If there is anything else going on that day, grocery shopping, appointments, school functions, meeting friend, the gym, which there is always something, then that takes away from my torch time. I find myself repeating "its ok, there is always tomorrow" I try to remind myself it isn't just what I did today but the accumulation of my efforts that will give the true picture.
