So many terrific comments in this thread. For me the best thing I've ever done has been to become involved with a quilt guild, a vast amount of talent. I think that this forum is much like a huge quilt guild with so many willing to share, teach and advise.
With that said, like others have mentioned, if your personality is not 'meshing' with this teachers style of teaching and you are dreading going to lessons....then I personally would in a New York second find another teacher. In teaching there are two important factors 1) an open and willing student and 2) an open and willing teacher.
As others have stated this is supposed to be an enjoyable journey.
