What is it?
Taking time to journal can be a valuable exercise to know yourself better. It is your own private resource that can help you hear yourself and record how you are feeling or what you may be struggling with. This can be helpful to better understand what you may be going through or allow you to return to a problem later. A journal can also help you identify patterns that can be helpful to address.
What do you need?
There is no one way to keep a journal. You can write on and with whatever is most comfortable for you and will allow you to look back at it later. When you start journaling, do not set expectations for yourself about what you should write about or what it should be like. GIve yourself permission to write whatever you feel like and do not be critical of your writing.
