Personally, I see journaling and gratitudes as important to long term health as training and nutrition.
It's a simple but hugely transformational practice that is common theme among some of the greatest minds that have ever lived. Improve your self awareness, take control of your narrative and learn what you need to do to make a positive change in your life.
Improved mood, acceptance, motivation and accountability. All from just writing a few things down each morning.
Listen, learn & put this into practice!
