The important reset is to stop the first miss changing the decision-making on the second chance.
After a miss, give yourself one simple cue for the next opportunity: see the goalkeeper, attack the ball cleanly, or finish through the target area you have chosen. Do not carry the technical detail of the previous chance into the next one.
Also judge the first chance honestly. A miss does not automatically mean the decision was poor. If you arrived in the right position and chose a sensible finish, the process may have been good even though the outcome was not.
Between chances, stay involved in the rest of the game. Press, combine, make another run. That stops your whole performance shrinking down to the last shot.
Good finishers miss. The skill is making the next chance feel like a new event rather than the continuation of the previous one.
