When I see people comment that they can only focus on code for a few hours, I feel like a freak. I can focus on any one thing for 16 hours per day, indefinitely. I don’t know why. I don’t use tricks. And it energizes me. I have very low social needs. I doubt I’m neurotypical. I doubt John Carmack is.
