Plus one for the importance of this.

Some things that I found very valuable to learn more about:

- Being more aware (present) of your thoughts and emotions. - Ability to get de-attached from an emotional situation. - Ability to tame the brain's obsessive thoughts. - How our bias affects our reality. - Separating what can be controlled from what is outside ones control.

Journaling has been extremely helpful to learn more about oneself and reflect. It is also fun to have a more detailed reference for a normal day you had 10 years ago.

P.S: Any book recommendations about the topic?
