I loved this idea for a lot of reasons. I think this would be great to do on a yearly basis with our kids individually or as a family until their old enough. All you have to do is answer one question a day and...voila...you have a journal! How easy is that?!
Below are some questions that Tricia had to go in the jar. This would need to be added to if you wanted to have one for everyday of the year. And the questions would need to be tailored to your family and/or each individual.
