A few words from Jim.
"Good results come from good technique.
Not so good results come from not so good technique.
Practice good technique and don't worry about the result.
Observe the result and change any errors in the technique you used, but only if needed.
Do what is needed at the moment, don't be overly concerned about what to do a few moments from now, you will action it then.
TRUST YOURSELF AND YOUR ABILITIES, DON'T OVER ANALYSE!"
