So I took action. I deleted thousands of emails I read and don't need or would never read from two different email accounts. I unsubscribed from newsletters. I went through my facebook likes and unliked many pages that were cluttering my feed and wasting my time. I unfriended some people as well.
I lightened my virtual load, and it's amazing how much quicker my scans of email and social media are, and how much more relaxed I feel in the process. It seems like a small change, but its impact is greater than I expected.
