It's just that after reading a post like that, it makes me think that I need a little bit more focus. I get attracted to new shiny things, but I still have a day job - which means that outside of shifting contexts a lot, I also shift my focus a lot.
A post like this makes me think that perhaps I need to dedicate a considerable amount of time to learning something new (Clojure in my case) and sticking with it.
And to answer your question, I did accomplish quite a lot this year (in my own little way). And I did enjoy it. Thank you.
