i was playing straight with a guy in north dallas who missed a gimmie and started jumping up and down; "why can't i play this game!" lol.... i think that a lot of players get ahead of themselves and fail to concentrate on the shot at hand drawing a false sense of security from a host of scattered balls.
here are some things to which i revert when i start playing poorly:
*when in doubt, shoot softly
*when in doubt, shoot the shot that leaves you the greater number of positional options .
*when possible, choose your break ball early in the rack. this will help clarify which balls to shoot first. if you know your break ball you can pick three or four other balls that will allow you to get position on that break ball. immediately you have taken four or five balls of the sequence until the remainder of the balls can then be shot to get general position on those last four balls.
watch this vid of neils feijan running over 100 and notice how he runs the rack. also notice how he blows his run. he looks unstoppable but then a SLIGHT mistake (perhaps he started to take things for granted) stops his run. it's an excellent learning vid partly because of the comentary. :

also get Jim Rempe's vids: "How to run a rack" and "How to run 100 balls" accustats has these vids. don't let Rempe's hairdo distract you though. YIKES!
oh, and download as many straight pool vids by mike segal as possible. i love his relaxed, gum chewin style. lol...
