You've got to walk before you can run, and also keep in mind that you are not a machine but a human being who will make something warm and beautiful, but not necessarily perfect.
A good way to start is to pick one print that you love for a feature fabric and then find solids and subtle prints that pick up the colors from it. Look for a fabric that has the colors in dots along the selvage. That will make finding the coordinating fabrics even easier. Another excellent alternative is to make a two-color quilt, such as a hunter's star.
I'd also recommend hooking up with a guild, if possible, and especially doing quilts to donate. You will find that just knowing you are filling a need will help keep you moving forward. An extra benefit: In our guild the fabrics for the charity projects have been donated, so you can get lots of practice without a big financial outlay.
