I like today and perhaps a little future still but the past is really something I'm not interested in. So as far as I'm concerned I like only the past of things and people I don't know. When I know I don't care because I knew how it was.
I try to make the good days great and take something positive from the days I'm not feeling good - work on technique or something like that.
You can't look at a glass half full or empty if it's overflowing.
