NaNoWriMo starts again

Signed up for the National Novel Writing Month again, a little reluctantly. I've done it the last two years without any real problem, but I wanted to take my time with the next novel, code named Life Portraits. I'm worried that I might not be able to stay focussed without the deadline of something like NaNoWriMo, so I think I will shoot for 50k words on the novel next month. That is really less than half of what I need for a first draft anyway.
