I've noticed that I've gotten lazy; as well, I'm super easily distracted and content to do little for longer periods of time. The following description that I found on Alan Jacobs's blog, text patterns, resonates with me:
Tom Bisell, from his book Extra Lives, an extended defense of the art of the video game and the value of spending large chunks of your life playing them:
Once upon a time, I wrote in the morning, jogged in the late afternoon, and spent most of my evenings reading. Once upon a time, I wrote off as unproductive those days in which I had managed to put down “only” a thousand words. Once upon a time, I played video games almost exclusively with friends. Once upon a time, I did occasionally binge on games, but these binges rarely had less than fortnight between them. Once upon a time, I was, more or less, content.
“Once upon a time” refers to relatively recent years (2001-2006) during which I wrote several books and published more than fifty pieces of magazine journalism and criticism — a total output of, give or take, 4,500 manuscript pages. I rarely felt very disciplined during this half decade, though I realize this admission invites accusations of disingenuousness or, failing that, a savage and justified beating. Obviously, I was disciplined. These days, however, I am lucky if I finish reading one book every fortnight. These days, I have read from start to finish exactly two works of fiction — excepting those I was not also reviewing — in the last year. These days, I play video games in the morning, play video games in the afternoon, and spend my evenings playing video games. These days, I still manage to write, but the times I am able to do so for more than three sustained hours have the temporal periodicity of comets with near-Earth trajectories.
