You prepare a to do list to make sure you get things down. End up you have too many items in the list and none gets done.
So now you have to manage the to do list.
Instead of one to do list with lots of items on it. Make 3 lists.
1. List with important and urgent items to do. Must finish it TODAY
2. List with important but not urgent items. Must do but still can wait to finish it. You still have time to plan and do.
3. List with the rest of items. Where you mix all other items in this list. You can then remove any items because they are not important after some time, or you can move items to list number 2 or number 1
