checklists do wonders for my anxiety.

too often i'll have a sudden thought about "oh, i need to make sure to fix X" or "I cant forget to pack Y before the trip". My options to deal with those sudden thoughts are:

1. Do it immediately, which isn't always possible

2. Do it later, which means that I'll obsessively stress out about it because "what if I forget to do it? I need to make sure this stays at the forefront of my mind at all times."

3. Put it on a checklist and give myself permission to stop thinking about it until its time to do it
