March 16th -- How much do you edit as you write, and how much do you leave to the second draft?

I generally try to only do spelling or grammar edits as I draft, saving anything deeper for revisions. I brought this with me from my day job doing marketing writing.

That said, this novel is literally my first foray into fiction writing...so who knows what my answer will be in 2 months. Or 6 months. Or 6 years...
