To truly turn your life around, you need to also control your emotions (which are subconscious) and work on being and staying in a positive emotional state as much as possible. You cannot do this by conscious thought because the conscious mind is not powerful enough. Instead you need to directly affect the subconscious mind. How do we do that? By reading from a positive thinking book, a few pages every day. Read for 15 minutes every day and never miss a day and long term, this will turn your thinking and emotions and your life around. I am living proof of it.
