Keeping a journal is a good discipline. It helps declutter your mind. And, so is good for your wellbeing and mental health. A Codex Vitae is the book of life. Your life. It’s where you write down your beliefs, strategies and life hacks. Plus, bits of wisdom.
This is your user manual, written by you, for you. You share with yourself, all the knowledge learned, how you are evolving as a human being. This is a book that you will sit and review weekly, monthly, even daily.
Do a yearly review in January of the entire document. Expect values, beliefs and hacks to change — don’t hold on to them too rigidly. Develop a habit of using the Codex as a repository for beliefs that you develop throughout the year.
