So, I frequently get up to take a break, and I forget what I’m doing when I get back.
To solve this, I create a page here: http://novaksolutions.com/next-task/
It gives you a place where you can type a note to yourself about what you are going to do when you get back from a break. Nice and simple! And, because most of the stuff we do now-adays uses a web browser, it fits right into your workflow.
