Social media is a fantastic tool for the modern age, but studies have shown too much can lead to unhealthy thoughts and attitudes about our lives. So this week instead of posting another killer selfie or hilarious meme, take a moment just for you. Write yourself a letter. With a little introspection, you can write what a younger version of you needed to hear. Or you can treat your future self to a nice moment by sending yourself a silly message to discover later. Either way you’ll be sure to benefit from your own words.
