In practice and in play, we all have strengths and weaknesses. Be honest with yourself about both. Practice to correct weaknesses and reinforce strengths.

It is rarely the last shot you played - the reason you clanged the hoop is because you approached it from a poor position, which you got into by being on the wrong side of the pivot, and so on.
