Correct one fault at a time. Concentrate on the one fault you want to overcome.
Make the basic shot-making decision early, clearly and firmly, and then ritualize all the necessary acts of preparation.
Practice puts brains in your muscles.

You have more potential than you think.
I hope I'll never get too old to want to take part in this event, and I don't think I will ever age that much.
