Each year, starting two years ago, I filled a mason jar full of memories from my year. I would start New Years Day and kept going throughout the year. Big memories and little memories alike, I would write the memories on a sticky note and put it in my little jar. I try to incorporate as much detail as I can and the dates of these great memories. On New Years Eve (or whenever I have time before that) I open the jar and read about all of my memories from the past year.
I would *highly* recommend this to everyone. At the end of the year, when I an engulfed with coming off the finals stress and accumulating the stress for the coming semester, it gives me some time to breathe, reflect, and feel blessed. Looking at the memories and the friends I have made over the past year and seeing how much I've grown gives me faith in the upcoming year and helps me see how blessed I am.
To do this, get a mason jar and label it memories. Then, each time something fun, inspiring, challenging, amazing, or hilarious happens, write the memory on a sticky note and put it in the jar. That's it. It's little to no work and you'll be so grateful you did it at then end of the year. Sometimes we all take our friends and out good times together for granted because we can be so consumed by stress and hardships. It's wonderful to look back on your year in a positive light.
