I typically make a to-do list at the end of each day so that when I start work in the morning, I already know what I need to get done that day. I typically write down from highest to lowest priority but I always put communication first so if there is someone I need to ask a question about or get in contact with, I try to do that first thing at the beginning of my day so that it gives that person an ample amount of time to respond and set up a time for us to talk.
