A moofable feast. - Running Around, Grown-Ups, and the Act of Doing
It is similar to what those of us who knit call a process knitter (someone like me who knits because they like DOING the knitting and learning new knitting techniques) as opposed to those other knitters that are product knitters (those people, like my mum, who knit things and who see the finished product as the only point of knitting).
Strangely, most other things that I do I am more likely to give up if I am not great at it and am not interested in practising or improving. e.g. writing, drawing, painting - things that I am not bad at but somehow do not have the urge to persist with.
