Some progress is learning which part of the day needs less pressure.

Not all improvement looks like doing more. Some of it is noticing that one stretch of the day, the early morning, the hour after lunch, the last part of the evening, has been carrying demands it was never going to meet. Pushing there costs more than it returns and leaves the surrounding hours worse as well. Learning where to ease off is real information about how you work.

Watch which hour you usually fail at this week, then move one demand out of it rather than trying harder inside it. Put something undemanding in the gap and see what the rest of the day does.
