I've been knitting for about 10 years now. A decade. (Sheesh, don't I feel old now ;) ).
One thing I've noticed, is how I've developed an affinity for knitting hats. More so for me than anyone else, but hey, I know I'll enjoy them - and I know what color/s to knit the hat/s in.
So, this year, I've actually challenged myself to knit as many hats as possible (desirable 52 - one per week) and I've actually started the process. This is mostly (but not entirely) due to the fact that I am participating in the 2010 Ravelympics. Ravelympics? It's a knitter/crocheter/weaver/spinner's version of the Olympics, where we challenge ourselves to make 'x' during the Olympics - from opening ceremony/lighting of the torch to closing ceremony/extinguishing of the torch. And everything needs to start and finish in between the opening and closing ceremonies. (I'm just a little excited about it)
So far, so good. I'm on hat #5. Granted I should be on hat #8, at least - but life is life and sometimes it means putting some things on the back burner.
On a different note:
I haven't considered myself a selfish knitter, until more recently (going on 4.5 months now). Personally, I've gotten a little fed up with people (more in face-to-face life) asking if I do commission work or make suggestions that I should sell my stuff.
If I really wanted to sell my stuff, I would be doing it already.
I do have a couple exceptions to the rule. Family and friends - more often than not, they are appreciative and take care of the hand made items.
