So you have your To Do List and you eliminated or delegated tasks (See post on 5/2/17 )
A good idea to make you more efficient is grouping or batching tasks or jobs.(See The Organized Librarian- my book - offered at this blog) This works well with small tasks or routine items. You can batch small tasks like filing, shelving, budget work, or items that require the same mind or time frame.
Some Examples: 1) Take all papers, mail, handouts, budget sheets to needed locations in one trip, 2) Do one project ( or section of a project) at a time . Work on it until completed or the task is completed before starting another task/ project, 3) Set aside certain times for checking emails, making phone calls, 4) phone contacts to confirm meeting times and places.
Work from your To Do list with 3 to 5 items per day. Focus on getting those items done. At the end of the day, you will see and feel accomplished .
