I consider myself to have about 1.5-2 hours of "genius" per day. I don't know if it really is genius, but during it, I'm operating at an intellectual level where I feel that I'm really making progress, and am able to grasp things, formulate clear questions and goals, and notice new connections.
After that time, my own thoughts start to elude capture, as if someone else's dream...
I can work longer, but I need to have a structured task - i.e. that doesn't require original thought, but is just a slog.
It's great to have a study to support my experience, and encourage me to value and nurture this "genius" time, with recovery time and activities.
EDIT at 1 hour per day, 10,000/365 = 27.4 years; say 30 years. If you are blessed with a naturally stronger constitution, enabling you to do 3 hours per day, you could do it in 10.
