There is a few important ones actually like :
- role model
- On time

- good listener
Sometimes coaches are so sure they are right that they don't even give a chance of the rider to explain his problem, we should, as they can feel something that we can't see .
And they need to be capable to ride their students horses and demonstrate what they are explaining, never been a fan of coaches who say: do what I say, not what I do.. :)
