Your life experience is always some total of what you focus on, what you concentrate on and focusing on. It depends on whether you are controlling the things that you have control over. Your experience of life is not what is happening in the external world but your experience of life is dependent on the kind of meaning that you derive out of what is happening external world.
So your perception of the world is highly dependent upon your mind set and your internal state. You look at the outside world and experience it based on the your own interpretation. So the beauty or ugliness of anything outside of you depends on your beliefs and meaning you give it.
So your life experiences -> your beliefs -> your values -> your thoughts -> your thoughts -> your feelings and emotions -> your behaviour and attitude -> your choices and decisions -> your results -> quality of life.
