Writing on a consistent basis affords you an opportunity to get to know what makes you happy, sad, anxious, confident, as well as see who and what is affecting you and when! It is a written mental map of your life. You can look back and see what triggers your negative moods and how to remove those stressors. It reveals the overall picture instead of just daily snapshots of your emotions. Do you seem to have a more difficult time during the middle of the week? Do certain co-workers make you more stressed out than you realize? Are you taking anger out where you shouldn't? Having your emotions clearly written down will help answer some of these questions. It will also show you how your emotions are affecting you when you don't even realize it!
