There really is no wrong way to journal, but I personally never took to the stream of consciousness, "morning pages"-style journaling. I've found that if I have a bit more structure, I can stick to it more easily. For instance, I've been doing some variation of Lynda Barry's daily diary for more than a year now. This video is the simplest version. Instead of a timer, I journal for four songs: 7 things I did, 7 things I saw, one quote and one drawing. Her books have a lot more variations, too.
