I was asked a question about planned vs. unplanned work. How do you manage interruptions that come up throughout the day?

My take on it is to put all my planned and unplanned tasks (things I just need to do but don't know when) in Asana, and any meetings on my calendar. Then, if a new unplanned task comes up, I first add it to Asana as well. It is the tool I use to capture and organize all of my todos. Depending on the priority of that new task, I assign it to myself for today, or tomorrow, etc.

That means that I often have to rearrange my priorities and the tasks I'll be doing today, tomorrow, and in the following days.
