I require more depth than just saying "practice"

im not fed up. I know i need to practice, however im not acqualizing any lessons learned. I focus using the hyperfocal scale. I click the shutter, i develop the fim and it is out of focus. and by looking at the negatives i dobt remember the perceived distance, the actual distance, or the distance that was read on my camera. What ia to learn from such an absensce of information. If i waste time writing it down, the opportunity has pasted. Is there something i can do consciously actively to practice?
