I recently wrote a letter of thanks to a guy named Jim, who helped me quite a bit when I was young man, sharing his time and knowledge with me. I posted about it on social media, and we’ve since reconnected. Write a letter of gratitude to someone in your past who shaped your present for the better or made you who you are in a positive way, then share it with them if you can and post it publicly (if you’re comfortable) tagged #LettersOfGratitude. Send us a pic of your letter and a link to your post.
