The first required step in journaling is developing a habit to journal every day. I mean "every day" metaphorically. If you miss a day, you haven't failed. But if you journal once a week or less often, you will not get much value out of the analytics, and, even more importantly, you will miss a lot of important happenings. For me, 4 or 5 days a week is "every day."
3-Minute Journal is a tool to help you keep track of your inner work life, and to power your own regular reflection. Deciding on and executing a plan of improvement requires understanding what has happened in the past that you want to change (or maintain). Recording your activities enhances mindfulness, and regularly tracking and reviewing what you do is critical for self-awareness. 3MJ supports all these objectives. All you need to do is take a few minutes (literally) each day to think about and record what happened.
