You have a day full of meetings with 15 to 30-minute breaks in between.
What can you accomplish that you can finish within that timeframe without returning an hour later and having to start all over again?
It might take a while to figure it out, but that’s the idea, to think about it and have it ready when those moments do popup so that at the end of the day you aren’t wondering what you wasted 2 hours of your time on.
