NaNoWriMo? No Chance!

So, a lovely friend of mine emailed me last month about NaNoWriMo (National Novel Writing Month).
"Ooh, that sounds like a good idea", I said, clearly in a state of denial regarding time and energy. "It would be fun to meet up with other writers and try to complete 50,000 words in a month!"
That month is November.
Not next November.
This November.
So I have signed up - created a username and password (instantly forgot both), uploaded my novel idea and begun online chatting with other writers.
And it's proving quite useful.
There are lots of seasoned writers who are on their 3rd or 4th books, who've self-published, and who are very willing to share advice.
However...
Is it just me, or does everyone else seem to have more available time?
People are meeting up for write-ins, getting 3,000 words written before lunch, starting 2 or 3 different ideas before settling on just one...  Generally, I'm feeling a little bit inadequate here.
Now, I know books don't write themselves, and I'm trying to write at least every other day, but with full time work  and full time parenting (I know that doesn't add up, but I teach English not Maths) it's difficult simply finding the time to sit down, switch my brain into gear and focus on my story. Last night, for example, my protagonist was trying to formulate her thoughts and plan her next move with 'My Little Pony' playing on the telly in the background. A tricky feat!
I envy those writers who have the time and space to actually write.
But then, maybe they're just more motivated and focused than me.
Something to aspire to.
I shall attend a write-in and let you know how it goes...
