I recently participated in a 7-day gratitude challenge. A friend of mine nominated me, and the directions were quite simple. I had to post 3 things a day, for seven days, for which I was grateful. I also was required to nominate at least 3 other people to follow suit and participate as well. I figured this was one of those challenges that would be easy, seeing as in my opinion I am and have always been an extremely grateful person.
