Being informed does not take a lot of time. But there are many wrong ways of doing it like reading what comes up on your twitter timeline or visiting a clickbaity site like CNN or reading any algorithmically-created newsfeed.

Here's what I suggest: subscribe to The Washington Post. Once a day, scan through the homepage and read through any articles that catch your interest. When you hit the bottom of the home page, you are done. Depending on how much you are interested in, this could take five minutes or twenty. You will get a reasonable overview of the most important topics primarily focused on the US.
