I've started journaling as a hobby. I've been writing cute stories about each of the grandkids, my daughter and her many hair styles, holiday disasters, how I was such a nerd in high school. I'm hoping to make copies for each of the grandkids and my nephews. I guess I started when my mom passed away and I brought home boxes of old photographs but had no stories to go with them: such as how they survived during the dust bowl etc. I wish I knew more about my grandparents, great grandparents, etc. But can't ask them now because they aren't here.
Anyway, its a very inexpensive hobby and so far has been getting positive reviews from the family. You could include stories about where you were when 9/11 happened, where you were when we put a man on the moon etc. Some historical, some fun, some nostalgic. So if interested in writing at all, I highly suggest this hobby. The writing just needs to come from the heart. Write for fun with no need to make it look like a college term paper.
