To quote the drummer from my favorite band: Practice. You're not going to get it on the first try.
Quilting is about trial and error when trying new things. I don't have a lot of quilts under my belt, but every one I have made has had something completely new and occasionally has frustrated me. The current one has had involved sashing, borders, tying with perle floss, t-shirts with fusible interfacing, and rotary cutting---all things I hadn't done before and sometimes it was frustrating, but I kept at it. Maybe machine quilting really isn't your thing, but you should do some smaller projects before you officially decide that it isn't for you.
