I work as an editor four days per week and have Fridays "off" as my PWD (Precious Writing Day).
My current WIP (work in progress) is a teen novel that I think will end up being about 50 000 words long. At best, on my PWD I seem to be able to do about 1000 words, which means that it is going to take at least one full year, minimum - especially when you factor in school visits, life interventions etc - to get down my first draft. Ouch!
Will I make it?
Because I can happily announce that I have already managed to get over 15 000 words down and that means I will keep going until I finish, no matter how long it takes.
I have many 5000 word "starts" on my hard drive - but once I have got over the 10 000 hurdle, history tells me I'm in for the long haul.
And that makes me very happy.
