Mindfulness in present moment is necessary to live the each day fullest. Once overthinking about things start we start to gain the loss in many areas and our life also. Each day is the new start. We self - Sabotage our self and ruin our lives. The sense of unworthiness and unwillingness to live a joyous life , that feeling of incompetence and the "lost" phase in our lives begin here. So be mindful and be positive. We have only got one life, why are we not running like fire toward our wildest dreams. Try Hard , fail , try , fail , try Fail even better then try even best. Universe would be in your favor.
