As a writer, having such a terrible attention span is very detrimental. I try to set myself goals for writing: "Today I will write 1000 words! At least!" but often it turns out to be "Hell, I've written 100 words, I can reward myself with some [insert mindless entertainment here]".
I'm planning to finish a novel in 2012, and I've been doing well so far, but some days it feels like it might be more like 2015 before it's finished. Perhaps it's time to go ask my doctor for some Ritalin. Right now though, I've got some shiny things to go stare at.
