subtle mentality shift

What is the subtle mentality shift I feel between winning day and losing day? It's not the feeling of being right/wrong. It's not the aftermath of victory or defeat. 

I think, losing lately is the feeling(result!) of abandon, of fck it. Winning is the feeling of keeping a grip on it. I need to recruit more of the "keep my grip" mentality, and not the "fck it" mentality. Probably also in other areas of my life.
