Becoming Bliss | Creating a Happy File

One of my favorite parts of college was being an orientation leader. Everything about it was so exciting. It's what made me really fall in love with my university, and then I became passionate about sharing that love with all of the new bulldawgs coming to Louisiana Tech. I became really close to fifteen people rather quickly, and they were like my little summer family. 
Becoming an orientation leader is what helped bring me out of my shell. While I do have my introverted moments (and many of them), I usually like to be outgoing and just outright weird (#ESFJ). Being an orientation leader brought me so much happiness in the simplest of ways, and one of my favorite ways was with the creation of a happy file. I guess it wasn't technically a happy file per say, at least not at first. I created a happy file on my own with the help of OSL. 
Being an OSL was like taking a class. We really had to learn about the university and take tests, and this was all done in a private little classroom. On the wall of the classroom hung paper bags with each of our names on them. We were instructed to write down nice things about one another and put them in the bags. This was done sporadically and randomly and pretty much anytime that you noticed your fellow orientation leaders doing something awesome. 
It always amazed me how I was viewed in the eyes of others. I never thought of myself of funny or clever or witty, but all of these notes said otherwise. And what did I do with these notes? I put them in what I now call my happy file. All of the little warm fuzzies that my summer family wrote for me were put into a file, and anytime that I'm feeling down in the dumps, I pull it out and read them. 
Since my OSL summer, which was in 2010, I've added to my happy file. In it are cards and notes that say nice things about me, pictures of amazing memories that I love to relive, inspirational quotes and photos and so many other things. Whenever I need a pick-me-up, I pull out my file. Just reading and seeing all of these things instantly pulls me out of my foul mood.
I know everyone has their different processes to pull themselves out of anger or sadness or any other unhappy emotion, but I want to challenge you to create a happy file for yourself. Pull out old greeting cards, print out some fun pictures, get on Pinterest or Etsy and print out or order some inspirational quotes or printables, scour the internet for memes or photos that make you laugh. Anything that makes you smile should go in your happy file. When you're not feeling 100%, take out your happy file and let that help you turn your mood around. 
I hope your day is full of happiness!
