After completing 14 days of the happy trials I am glad to say this really does work. The effects are subtle, but over all I have gained positively from the experiment. The breakdown of what I did:
Every day when I woke up I would smile. With 2 days of exception, this would give me great joy and I would be happy for at least an hour without trying. As I drove to work, prepared the day, or arrived at work, things just seemed more beautiful, more captivating.
Nearly every day I went outside I was awe-struck at the beauty of the sky (even cloudy days!) and found myself nearly mystified by my surroundings. Some days I continued the smiling throughout the day, and would usually giggle or laugh a little to myself at how great I felt, and often, too! This caused me to be even more happy, and just was wonderful. Enjoying an hour or so of utter content with myself and where I was.
A few days I did not attempt to be happy on purpose but found it was nearly unavoidable. Friends seemed funnier, events seemed more intense/exciting. Dancing was easier, talking was smooth, there were no negative affects.
The two of the 14 days however, I got little or very bad sleep. I woke up and attempted to smile but it did nothing, no goodness came out of it, and merely felt like muscles in my mouth were moving (that was the extent). But these were towards the beginning of the experiment.
Today, I am not trying to be happy, but as soon as I think of any emotion, I trigger a memory of this study and all the happiness and joy attributed to it, and I cannot help but smile!
What a great day. I love everything :)
