You may have stopped using a diary once you reached adulthood. But the concept and its benefits still apply. Now it’s called journaling. It’s simply writing down your thoughts and feelings to understand them more clearly. And if you struggle with stress, depression, or anxiety, keeping a journal is a great idea. It can help you gain control of your emotions and improve your mental health.

Journaling is not just a little thing you do to pass the time, to write down your memories—though it can be—it’s a strategy that has helped brilliant, powerful and wise people become better at what they do.
