Creating your own worksheet, not so much. I wanted to use these nifty checkboxes I just discovered on Google Sheets. For When, it was fine. For Where, it was far too limiting. Better to just do it the way she presents it. I do think this really helped me think about how I want to sort messages and what categories make sense for me. I am still working on getting the sorting system to work for me, though. I tried it through gmail for one of my accounts, but the messages that appeared in the Google mailbox don't correspond in my Mail client. I really prefer Spark email and use that for my work messages, but I have not started sorting those yet. I really like the principal, I just need a little more time to get the kinks worked out. Thanks Alexandra for a lot of useful information!
