The closer I'm getting to the competition season the more I like to work on my focus.  I feel this is a huge element towards being competitive and confident.  How many times have you done a sloppy transition or a bad line to a jump and just past it off as a mistake and went on with the rest of your workout?  Have you ever jumped a fence and talked out loud your error before even landing?  That is lack of focus.  With concentration on doing all the components correct the first time, there will be less margin for error in the future whether working out or at a show when it really counts.
