Mr. Ernst’s Answer
As far as training goes in any interests in your life, it should be a daily factor. Everyday you should be training your mind, soul, strength and body. Set up specific reps and scheduling dealing with the outcome you are looking for concerning your physical health. After that set up time and find quiet locations in order to bookmark PDFs, read books and research online topics dealing with Criminal Law and Justice coupled with Sociology and Psychology. Last but not least meditate, study and become the art as well as the profession you are seeking.
I wish you the best on your journey.
