I think the most important thing is figuring out what kinds of quilts you like to make. I have had the experience of starting a project and find that the style or construction does not fit my temperment. I get stuck and then realized this is not for me, For instance, I like piecing but not intricate piecing.
I often do a pattern several time. I like the way that different fabric yield real differenct results. Quilting should make you feel good. You are the designer so do what you like!
