NaNoWriMo - This year?

I did the whole National Novel Writing Month (NaNoWriMo) thing last year. I'm not sure I have a novel in me this year though.I have some ideas... It might be a sci-fi novel set in space. That's the only concept I have fleshed out enough to even have a shot at the 50,000 word mark this year. I'm sure I can do it... but I think I have to focus on getting myself another employer.Writing almost 2000 words a day gets hard after the first week or so. Then it gets exciting again for the last 10,000 words! It's a high like finishing a marathon.But I don't think I can handle it this year.(Can you sense the internal struggle? :-) )Maybe...
