I understand this fear concept very well. I can make any excuse not to do something that I think will be difficult. I encounter this quite often in quilting. Sometimes I purchase a kit or pattern that I have to have. Then I find myself making all kinds of excuses not to start it. I have a cupboard and three drawers of such projects. I go gun ho buying everything I need for the project and then it sits and sits and sits.
Now here I am setting up a website for selling these projects. Don't tell anyone, but that was my plan all along!!!!!!!!!
