Late October I decided to take the plunge and attempt NaNoWriMo. I haven't done much writing in some time and thought it would be a fun attempt to jump back into things. So far it's been pretty fun getting back into writing about something I hashed together from a weird dream.
But I'm also woefully under the NaNoWriMo average at 8111 words. Most of my writing happens during my train commutes to and from work via train. I've averaged to about 400ish words a day, which wont get me anywhere near 50,000 in time.
My problem is that as soon as I get home again, I'm hit by a huge bout of lazyness. My afternoons and weekends are spent slacking off or doing other things around the house. It's not that I don't have things to write; as soon as I sit down at my desk I'm hit by a huge desire to do anything and everything outside of being creative. It's like some sort of lingering nerosis from avoiding homework as a child or something. This sort of thing has also plagued me in the areas of drawing as well.
What should I do to overcome this almost aggressive form of lazyness? Should I rearrange my desk/room? Should I leave my PC off and just focus on my MacBook (the one I use for writing on the train)? Should I go to a different room entirely?
Edit: I want to note that I'm not actually stressing out over the 50,000 word thing. That may be the "goal" of NaNo but it's not the true goal behind the event, if you get what I mean. This is more about me being disappointed in myself that I have had the time in which I could have caught up (2 weekends) that I totally wasted due to this problem of mine.
Edit 2: Okay, so to rephrase this question: For someone who has had a similar experience, how did you overcome this type of inability to devote time to writing when at home?
