Pool is all about "focus, focus, focus," ( at least thats what Tom Rossman told me). your focus can be (is) greatly affected by your attitude. You want to keep close watch on those 2 things, and make sure there were they need to be. Once your head comes away from your shoulders its all over.
I have a few shots I like to shoot, when things start to get out of line I'll find a table and fire away at these. 2 are basic 2 are for fun...
Make sure you know why things are not going good, if its because the first 2 things I mentioned then you need too put yourself in check. If its because your being out played then you better be learning somthing. If its the rolls, well thats the way it goes somtimes...
Losing 5-0 too sombody you think you should beat 5-0 sounds like you dont know his, or your true speeed, or its a focus problem.
