Well one thing you have to internalize is that quilting and learning to quilt is an ongoing process. Unless you are truly one of the gifted "artises" amongst us you will never know it all or be competition worthy! I have been sewing since I was 10 and quilting for 15 years and I am still learning new things and refining my skills and I am still just a mediocre quilter.
If you are a perfectionist? You will have a hard time. If you're a life long learner than you've found your craft!
And I agree with hazeljane's quote... it IS only fabric and no one will die.
