Don’t meet writing goal

I am working with a writing group. Every two weeks we get together and share something we’re working on. I find myself writing just enough to have something to share. I want to write 1000 words a day. I have a big list of memories to write about, and writing that much takes me about 30-40 minutes, so it’s not a huge time or inspiration commitment. Yet I most often don’t do it! Then I get frustrated with myself. I’ve written up a model, but still feel overwhelmed and lost in it.

C – I don’t always write my 1000 words a day goal
T – I must not really be a writer
F – Lazy
A – Do piddling things instead of writing, do house work instead of writing, take care of others before writing, imagine that am getting writing done even though I’m not doing it, write at last minute to meet class deadlines, don’t meet my word goals.
R – I am not a writer because I don’t write.
