Some people keep a daily journal, while others prefer to write once a week or even once a month. Start by giving yourself a schedule to get in the habit of writing. Commit to spending ten minutes writing in your journal every morning or every evening.  Try writing "Morning Pages," the creativity tool that Julia Cameron popularized in her book The Artist's Way. Each morning, before you do anything else, write three full pages, longhand, in a notebook. Don't check your work or think too much about what you're writing – just get it out.  Try keeping a monthly check-in journal. At the end of each month, write an entry about the main events that happened. Explain what happened, what you loved, and what you learned. Track how you grow and develop each month. If you are pouring your deepest, most vulnerable thoughts into this book, then you probably don't want anyone else to pick it up and start reading. Carry the journal around with you for safety and convenience. Alternately, hide the book in your home or office: under your mattress, or behind other books in your bookshelf, or in a safe or lock-box. If you're keeping a digital journal, make sure to protect your documents with a password or save them to a hidden folder. Every once in a while, read over what you have written in your journal over the past few weeks or months. Flip through the journal entries that you wrote years ago. Compare the way that you thought about things then to the way that you think about things now. Remember the past so that you are better prepared for the future.  Notice how your journal entries sounded at a time when you felt sad, stuck, or frustrated in life. Try to catch yourself when you are writing like this so that you can do something about it. Notice how you were writing at a time when you were happy and excited about the future. Think about how you can channel this feeling.

Summary:
Write regularly. Keep your journal safe and secure. Use your journal to understand your growth.
