If the doors of perception were cleansed every thing would appear to man as it is, Infinite. For man has closed himself up, till he sees all things thro’ narrow chinks of his cavern. ― William Blake

You will not be so easily able to stop. I know you’re stubborn, but it does not matter. The more you’re stubborn, the better you become when you’ll finally manage to change. 
Carlos Castaneda
