Well said Clark!
A senior student at my dojo told me once that trying to be perfect all the time is great, but you're never going to be. He has been practicing for more than 15 years and said that now he's pretty happy when he does 4 out of 50 techniques perfect!
I would say don't hold yourself back from learning new things. You have the rest of your life to work on the details!!
