ADD Tip: You can change the goals on your to-do list!
As your needs and your situation change during the day, don't be afraid to cross out and replace items on your to-do list.
And if you accomplished something that wasn't on your to-do list, write it down and check it off!
This will help you maintain a more realistic idea of your productivity during the day, as well as identify any particular things that may be hindering your productivity or taking up too much of your time.
