Caeleb creates a to do list at the beginning of each work day. He makes a list of tasks, estimates the time needed to complete each one, and arranges them so that he works nonstop from 8 am until 5 pm. What should he do differently to most improve his time management? Stop estimating the time needed to complete each task. Include only parallel tasks on his to do list. Color-code the tasks on his list by order of importance. Schedule time for mental breaks
