I have been knitting for 10 years. I have knit for almost every single one of those for 3650 days.
In those 10 years, I have knit slightly more than 300 projects. For several years now, I have listed all my sock knitting as one sock parade but only count them as one on going project on Ravelry, where I track my projects. I knit between 8 and 10 pairs of socks per year so added to Ravelrys 279, plus the socks, I feel pretty comfortable with the number.
In 10 years I have accumulated enough yarn to keep me knitting for the rest of my life. I could knit 10 sweaters a year for 10 years and 10 pairs of socks and 5 shawls and I would still have a bit left. Incoming yarn doesn't quite keep up to outgoing yarn, and that's ok. I can knit as much as I want and I will still have yarn.
I have a library of wonderful inspiring books about yarn and yarn things. It keeps the creative juices going and the dreams going even when I can't knit.
It changed my life in a hundred ways, and I am thankful.
