I have a few areas... I list myself as a Skillshare instructor, only because I have the one course that is live, but there are many areas that have slowed me down. Some of them are personal, and self doubt in my abilities. But beyond that, the area of providing a quality class stops me in my tracks because I tend to be overly critical of my class videos once they are done. Falls in the area of taking too long to produce a class because I constantly find fault in what I have produced.
