When you get to the point where you need an assistant to help with your calendar, you also have to start pre-empting any attempt to grab a small free slice of time. So my admin just blocks out everything by default, kind of like this.
@wendynather I always admire the people willing to do Calendly. For some of us, that would be like throwing a ball of Velcro into a dryer full of socks.
