Question: *What's your favorite lesser-known productivity or efficiency tool?*
I'll start with a vote for Momentum, a Chrome browser plugin I heard mentioned on the +Tim Ferriss
podcast. I'm not affiliated with it in any way, but I started using it a week ago and love it. When you open a new tab in Chrome, it shows a beautiful picture and what you've defined as your focus for the day.
It is a nice, subtle reminder of the big tasks that you need to tackle that day.
