You need encouragement! Well Girl! You came to the right place! These Board ladies know how to dish it out!
My recommendations:
1. Quilt charity quilts. The recepients will love getting your quilting.
2. Take a local class with an encouraging (if she's not encouraging, put it behind you and find another) instructor who gives you plenty of time for experience
3. Try something easy first. Say, a sepentine stitch at some angle across the quilt not hitting any intersections, using a walking foot made specifically for your machine. It doesn't need to be in "straight" lines, just lines.
4. Give yourself permission to be less than perfect.
5. Enjoy what you're doing
6. Reward yourself for taking this new step
7. Do not point out any errors (and there will be some), just learn from them.
