I remember reading somewhere that it's 90% mental.
That sounds about right to me.
The body, it just dances in the background. The mind is the real star of this show.
It's not even a very good show. Full of deceit and trickery. Empty promises and false praise. It drags on for far too long, and there's not really an ending. The lights just fade, ever so slowly, until you realize that the show is over.
It's not a very good show, but it can still mesmerize you and suck you in, if your amenable to that sort of thing. If you're not careful. If you're weak.
But, as they say, The show must go on.
