I bet if you ask for certain skills it will be'can't do that as got to see to the others etc'
My OH always says 'if you can't do teach' A lot of tutors are makers but not commercially successful but don't throw themselves into teaching.

I teach to impart the skills that I consider I have improved on from formal teaching to help people to get going, faster ,better etc.

Don't lose faith in yourself because of this experiance, rise above it !!!!!!!!!!
