0 Total self control is impossible

I can't control how my mind gives naration about anything. When I watch movie or news, authomatically my mind is busy with all kinds of narations. I can't even quiet my own mind. I can consciously control it for few seconds or at most minutes. I can somehow control myself to watch or not to watch certain news, movies or stories, but once I watch them it is too late to control how it affect my mind.
     Same as food, I can choose what to eat and what not to eat, but once I eat, I have no idea how my body handles them. The process is automatic and beyond my control.
     Feelings and thoughts are mostly automatic. I have very little control over them. It's hard to me to persuade myself to love what I don't love, to believe what I don't believe. I can't control what I don't really understand, how the mind and body work. Most people don't even understand themselves and yet try to control others.
     Actually I can only control the input, but not the process and the outcome. I can lift dumble everyday but whether or not it can shape my muscle, I have no control at all. I can read a book everyday but whether it can make me smarter or wiser, I have no control at all. Therefore I should only care to the input and maximize it.
