Writing problems

So I’ve been trying to write some things lately and I’m having a definite problem getting words down on paper. Well, words onto the screen, technically, but you know what I mean. I feel like I didn’t always have this problem, as I was at one point in time quite a good writer. Maybe it’s that I haven’t been writing much seriously in years (the only significant thing being my thesis), but I feel like I’ve even lost the ability to write any type of serious piece of work. Even blogging seems to have become more arduous than I remember it being (which perhaps accounts at least in part for why I’m not posting as much these days).
It’s something about focusing on one thing for any length of time which seems to be causing me trouble, although in this case we’re talking about focusing for a period of time on the order of… minutes.

Anyway, it’s frustrating, and it’s obviously putting a damper on my work progress.
It could just be a question of being out of practice, in which case nothing is going to solve it except getting back into the swing of things, and… well… practice.

Perhaps posting here more frequently will help. I don’t know, but it’s a reasonable motivation to try writing more regularly.
