Clear or cloudy you must understand the body does not care. It preceive it all the same real or imaginary. And so it is propelled toward the place the mind abides. There are no secrets from the body that the mind can hide. So think about things that are lovely and things that are virtuous. Imagine yourself successful, don't let your mind be aimless. See the fruit of your labor before it is in your hands, than you will never stop no matter what life demands. Think about what you want and not what's before you. Let you words speak life and actions be percise. Focus on your goal and never let it go.
