I wonder too -
I know that my skills are "better" than some - and "not nearly as good as" many others.
There may be an "ultimate quilter" out there - but so what? I put that in the same category as "fastest runner" etc. Right now I'm grateful when I can shuffle from point A to point B.
I am also reasonably sure that my skills may deteriorate when I get very old and/or feeble.
