I wish I could do that, but if I don't take breaks, I get headaches and visual migraines. Which is scary.

Going back to finding the right balance. I think the ideal, but practically difficult in the modern day - rest just as intensely as your work when its done. The alternating between working tasks, passions and rest increases future capacities. A practice cultivated an noted by Da Vinci.
Its difficult, If you have a big family, as "resting" is often housework and visiting relatives, and stuff. No real downtime, unless you're prostrate with the flu, and I've cooked dinner and washed laundry with a high fever, or whatnot.
Yes this is what I'm working on. Not well, but I'm working on it.
