One thing I've noticed is that I've become a much better writer. I've also discovered that I become accountable when I say I'm going to do something. For instance if I say I'm going to start eating healthier, well I have it there in writing. It is also great for remember things. It is rare that my wife and I argue but when we do I always have my facts straight because I can go back and look up specific things. I do only write positive journal entries, so I don't every write negative things about the people in my life. I discovered once you start a good habit they are just as hard to break as the bad ones. Writing is a habit now. I have to do it each day or my day just doesn't feel right.
