I struggle with calendars and how to manage communicating “availability”. Simply publishing your calendar or considering every unbooked space as “open” implies you’re just waiting to have a meeting. In reality those tend to be the most productive times!
Daniel Gross communicates it well in [this post](https://dcgross.com/improvising-for-productivity/ “Improvising for Productivity) on productivity:
Time isn’t the correct index for a schedule. Time doesn’t know when I’ll be in flow. White space in the calendar doesn’t mean I’ll be sitting at my desk, twiddling my thumbs, just waiting for someone to call. It usually means I’ll be working. When I mis-fire and schedule a meeting for when I’m in flow, it can cost me double the meeting time. Breaking the feedback loop of flow with a meeting, notification, or anything else should be illegal. And time-based scheduling often causes it.
