I have found three important reasons to journal and I'd like to share them with you. Journaling creates space for thinking -- everyone needs to process the day's inputs and outputs. Journaling helps create an anchor for your memories and what you learn. You can have more insight about your life and it can be captured. Journaling is an instructor as few of us have a mentor or counselor. How fast you grow depends on the amount of learning from mistakes and problems you can solve.
