I might agree with that, except we did Koshi Nage techniques a few classes ago, and I completely froze and was unable to do them at all.
You were aware of what was happening and why. This is real growth. That is the first, critical step towards changing response sets in behaviors that are mutually incompatible with freezing up. Patience, acceptance and self-forgiveness when things happen that you don't want to happen are necessary for positive change.
