Journaling and meditation are two powerful practices to gain more awareness of the thoughts we have. Very rarely do we have physical barriers in life. They are almost always limits that our minds place on us. These techniques help you get to the source of an obstacle and uproot it.
Take the time to write these out and over time you'll start to gain more and more awareness of the thoughts that you have every day.
Meditation is a way to stir up sub-conscious thoughts and journaling is a way to tangibly tie them down to paper so you never forget them.
