Monday Hour One questions!

Hello! I just finished the course on Monday Hour One and I had a couple of questions:

1. What if after my Monday Hour One is done, I forgot to put something that I should’ve put on my calendar that I have to do that week?
2. Would be going to the gym or reading be a part of Focus Time if that’s part of my goals? Would “work” be acceptable as Focus Time if you don’t know which project you are going to be working on that day?
3. Is Overflow Time the time you didn’t schedule anything on your calendar? If not, how would you schedule that?

Thank you!
