Hyperfocus is great until you need to stop. You're deep in something, the meeting is in 20 minutes, and your brain says "I'll wrap up in 5." It's never 5. A backward plan for transitions gives you the buffer between tasks that your brain won't create on its own.
Closing the current task, saving your work, context-switching mentally, getting water, using the bathroom, opening the next thing. That's 15 to 20 minutes of transition. It feels like 5. If you don't budget for it, you start every next thing late.
A calendar reminder 5 minutes before a meeting isn't a plan. It's a panic button. Ready Time builds a real transition: save your work, jot notes on where you left off, take a break, review the next task's agenda. Each step gets a notification. You're not yanked out of focus; you're guided out of it.
