How do you manage the really big projects? Do you put the whole thing on your to do list? Do you break it down into a step by step process and then put all of it onto your list?
Or do you save yourself the stress and put just the next immediate step or two on your list?
I really recommend the second option. Big projects are stressful enough without seeing the notation "Renovate Bathroom" on your list day after day for weeks on end.
Nor is it much fun to see the whole thing written out on the list you consult several times a day. The lack of checkmarks beside those items will make you want to give up.
You can make up an overview list. In fact, it's probably a good idea. Just put it away somewhere safe. Take it out once a week to see what needs to be done in the week ahead. And have some fun crossing off a bunch of things at once.
