Structuring the day can help if you're often feeling scattered or not as effective as you'd like to be. To maximize your time, these quick thoughts might help.
Here are some ideas:
Remain Present: At work, be present at work. At home, be present at home. If working from home, use a specific area clearly defined for work. Exit the area when not working. Whatever you're doing, do it as present as possible. A distracted brain leads to a distracted life.
Make a schedule: I use Google calendar for everything, but there are many great tools for scheduling these days. Schedule bathroom breaks, shopping trips, coffee/tea, lunch, phone calls, exercise time, meetings, followups, promises, activities that interest you. Anything and everything important goes on this schedule.
Prioritize: Now that you have everything on your calendar, start doing days and see how it goes. Did you easily fit everything in? If so, how does it feel to have extra time? Did you get hardly anything done?Time to prioritize. Look over your schedule and point your attention in the direction of what is most important or crucial to attend to. Place these activities at the top of your list. Do these things first. If you run into a insurmountable obstacle, move to the next task. If something takes a bunch of your time (unless you're being nicely paid,) it may be worth hiring someone else to complete the task.
