#1: Upgrade Your To-Do List
Instead of listing all your tasks under a single to-do list, create 2 separate columns and name them "Priority" and "Open" respectively. Limit your "Priority" list to a maximum of 3 tasks but you can have as many as you want under the "Open" list.
Here's the catch, you can only add to the "Priority" list from your "Open" list after 1 out of the 3 tasks has been completed. Through this discipline, you will soon realize that for you to work on anything at all, you will inevitably neglect most tasks, and doing everything at once is not an option either. This helps you to embrace your limits and better allocate your time daily.
#2: Learn to Control Your Calendar
With scheduling assistants giving unfiltered access to your work calendars, it is a matter of time before all the available slots are filled up. Learn to block out meeting slots on your own calendar to safeguard the time needed to work on your tasks.
#3: Limit Multitasking
Learn to focus and finish the task at hand before moving on to the next. You will be less prone to making mistakes and end up saving much more time than you think.
