Getting things done means you need to focus and prioritize on the activities that are important and essential. Take action on the tasks that you have determined that you need to do today or this week. Don’t get caught up on activities that aren’t due or urgent. I suggest not picking more than 5 items from your task list per day. You need to be your own judge of how many items you can reasonably get accomplished when you are juggling the other daily demands of meetings, e-mails, phone calls and interruptions. Initially, select 5 items from your task list, but you might need to reduce that amount depending on your job and workload. Then if possible, focus on those tasks in the morning and get them out of the way before your day gets busy and full of interruptions.
