Monday Hour One | New stuff keeps popping up in my head during the week

I’ve started Monday Hour One. All the to-dos from the download are scheduled in my calendar. And while I’m executing the to-dos, other to-dos pop up in my head: ones that weren’t in my initial download.

I don’t want to deviate from my planning, so I try to remember to plan the new ones later (meanwhile getting pretty anxious).

Can I do multiple Hour Ones in a week, or do I collect what pops up in my mind and plan them at the end of the day?
