You go in the weight room and you lift weights and you do all these things to strengthen your body. This is strengthening your mind. When you can stay focused and you can use that focus to always come back with your breath to center yourself, so that you're kind of floating in the moment, in the spirit.
Love and appreciation are identical vibrations. Appreciation is the vibration of alignment with who-you-are. Appreciation is the absence of everything that feels bad and the presence of everything that feels good. When you focus upon what you want - ;when you tell the story of how you want your life to be - you will come closer and closer to the vicinity of appreciation, and when you reach it, it will pull you toward all things that you consider to be good in a very powerful way.
