hi people. I do get nervous before a performance but not bad enough to make me mess up, or forget anything. my problem is that i always lose continuity during a performance. i have a harder time keeping the big picture tiogether.  anyone else have that problem? more iomportantly, can anyone else HELP me with that problem! how can i think in  a "straight line" ?! ?!
