That’s what practice is.
During a class if someone makes a mistake I’ll ask them to do it again. Not the mistake of course, but what they were doing that led to the mistake.
It’s great when we get things right, it shows that we know what we’re doin’.
A mistake shows that we don’t know what we’re doin.
No big deal.
See your “mistaken” process.
See how and why your mistaken process arises, then adjust your practice and process accordingly and do it again correctly.
