All fantastic advice...one of my favourite sayings is "Procrastination is the thief of time" and it truly is. So step boldly to your work table and just do it.
There are so many stunning quilts made and displayed by members here and in the various books and magazines. It is easy to be discouraged and try and strive for some kind of imagined perfection. But go back to the beginning, look at antique quilts, take a look at the Gees Bend collection and the work of the Tutwiler Quilters, such quilts serve as a reminder of what the art of quilting is. There is true beauty in their honesty.
