Attention (cont.)
DON’T FORGET TO START AGAIN!
For the next 50 min. time period, you will probably begin to notice diminishing returns from that 5 min. break. You might find that you need a 10 min. break.
At the point when your breaks begin to be longer than your study sessions, take a siesta, hiatus, run around the block, swim, trip to the laundry,... get the idea?
