A bit of an "let's overcomplicate this" kind of question
I pull out tomorrow's file this morning. Some stuff I simply toss in my inbox while other items just "hang around" on my desk or so ... waiting for tomorrow.
I could pull tomorrow's file on that day. I don't: I don't have enough heads-up time that way. Seeing a theater ticket today for tomorrow I can say "oh yeah, darling, we we planned to XYZ"
I could pull tomorrow's file at the end of today. I don't: it only shortens the lead-time but I'm still "stuck" with where to put the items.
So, for now I just have the stuff "around".
