An effective journaling practice is to respond to the same question over a period of time.
Ideally, you do not look at your previous answers until a set period of time has gone by.
While you are answering the question, it may seem like you are answering it the same way, but when you review your answers after the set period of time, you are sometimes surprised how your answer changes.
This can be used whether you are answering the question daily, weekly, monthly, quarterly, or yearly.
Sometimes it is interesting how your answers change over time. Sometimes it is interesting how your answers become deeper over time. Sometimes by the end of the process, you have a totally different answer than what you started with.
