We all, to one extent or another, alter our mental state. If we go for a run, it will change our mental state, if we take a tylenol, drink green tea, shoot up heroin etc. All of it changes our state of being. Whether these things are for the better or worse is largely subjective. Only we can answer that for ourselves. I'm curious though...
What do you do, take or subscribe to in order to change your mental state for the better?
