The most effective way I’ve found to build real focus stamina is by using visual time cues.

I treat my study sessions like interval training. Instead of one long, exhausting slog, I do several "visual sprints."

One of the reasons we lose focus is "temporal fatigue"—the mental exhaustion of trying to track how much time has passed while also trying to learn.
