One method that aids me in keeping my spirits high is my Positive Aspects Notebook. I started keeping the notebook after reading about the concept in Esther and Jerry Hicks' book Ask and It Is Given. The book states to use a notebook that is pleasing to the eye and to start every entry with: Positive Aspects of _____, then write about only the positive aspects of anything in your life.
With my notebook, I went for simplicity and just used a Mead marble notebook. Inside I have documented positive aspects of vacations, my car, friends, family, and more. My notebook is dear to me, worn and falling apart. Whenever I am feeling gloomy or down, I open my notebook and read all my entries. My notebook isn't entirely filled and I don't write in it every day, however, the positive feelings it gives me after reading, is worth the time spent documenting positive moments.
I recommend everyone keep some form of a Positive Aspects notebook for sanity and to show that life isn't as bad as we often make it out to be.
