It's mostly mental. Take care of your body so you can get enough energy. Spiritual energy fuels discipline and will power. What you feed you mind interacts with your spirit, the mind is the interface between spirit and body. If you pollute your mind, you pollute your spirit. If you pollute your body, you will gravitate towards high energizing content for a quick fix. But that kind of stuff is arousal or fear based and comes with a cost.
Clear your mind. Use salt water to clear. Build a team of spiritual helpers to protect your space and stack it full. Remember the faith of your youth. Faith doesn't mean you know the answer but that you are in alignment with Truth, with a Higher Intelligence that cares for you because you are part of it and it is part of you.
